Nicely done rougelike, with good visual appeal and some bugs... + randomly generated dungeons + great Boss design + taming System + can choose between difficulty ingame (for more rewards etc.) + detailed npcs + charming anime models + great OST + limited weapon and skill arsenal, but well executed + funny shopkeeper (has the hunger to kill me) + many effects + wellmade weapon graphic variations + detailed and themed dungeon design + great armor/costume design + can be used for some basic outfit modding (which is great) + simple story + fun and engaging gameplay + good combinations in fighting styles: raising monsters to fight beside you, weapon choice, hybrid gameplay etc. +/- much RNG based, so a solid build is diffcult ( I went with a Sword-Melee-Speed-build with shields, selfheal and dodge mechanics + Monster and Fairy magic ranged built - dialogue close-in on 3D Rendering is blurry in 4k - some weird bugs (bouncing of walls, gaps in the ground, stuck between structures etc.) - some trnaslation error - missing some QoL to fight against the hard RNG in the game (like rerolling, or scope down the RNG, some confirm buttons etc.) - taming system is good, but missing some QoL as well to make it more appealing (upgrading is a pain, overview is also painfull) + looks great in 4k Conclusion: Rustil is a fun roguelike game, which is fair to its user in some aspects, you can choose progression with/without risks, which is rewarding depending on the risk. The weaponsystem is simple to manage and possible builds you can count on your fingers, but you have other options like pets-catchign and building as a companion, also cycle through your wepaons of choice is great. Nonetheless is quite fun, but plagued with some bugs, which you can counter against with "unstuck" or specific scrolls. Magic is OP again (which is not my forte). I choose physical sword built and its pretty much doable above floor 500 in Endless mode, when you know what to do. The Game is visually appealing and has a great OST and some memorable boss encounters, but falls short in variation when you go through endless mode. The story is simple and you get to fight a lot, a whole lot. while at times its pretty chaotic, because of effects and enemy count, the fps goes down the drain, the game can somehow manage it, which is good. also the RNG is really high here, so doing a specific built tends to be more as challenge. As a work from an indie dev its quite good and enjoyed every minute of it. pro-tip: activate auto atk or you are in for a world of eternal hand-pain Score: 90 13/10 Those thieving cats! 13/10 Black armor with pink hair style <3 1337/10 Seraphyrus best!
Floor 127 takes a while to load, because floors 5 and 8 are larger floors that require you to simply find the exit rather than defeat all the monsters. The tower in Endless Mode loops every 51 floors and not every 50, which is why this is floor 127 and not 125. I use a scroll of sensing to reveal the entire map, and check it for any rooms with three treasure chests or souls of heroes. Nothing else is worth the time. The rooms with three treasure chests are "monster houses". These rooms are mostly safe until you try to open the treasure, at which point about 20 monsters appear to defend the treasure. On the way to the monster house, the floor 30 boss has randomly spawned. While I reached my maximum level of 52 dozens of floors ago, the monsters continue to level up and scale as I go further in Endless Mode. This level 30 boss is level 138 and it is quite sturdy, but otherwise not a challenge. I have 100% chance to ignore stun when hit, 50% damage reduction while attacking, and every time I use my completely invincible dark souls roll, I gain a 3 second shield equal to 23% of my maximum health. I can stack multiple of these shields, but the boss only hits me for 8% of my health anyway. If I perfectly dark souls roll through an attack, my attack speed and critical chance are temporarily boosted, but I also want to occasionally get hit because I'll counterattack with a -50% defence debuff. I activate Berserk, which multiplies my strength by 5 and allows me to do actual damage to the boss. Berserk has a long 25 second duration and has no cooldown - it simply needs to be recharged between uses. Amazingly enough, hero abilities like Berserk are able to be charged while they're active, so it has very good uptime as long as there are enemies to fight. This boss likes to run and charge at you, and I fight entirely in melee range, so our fighting ends up taking us both to the monster house. Dozens of monsters spawn to protect the three treasure boxes. I don't care. I can't be stunned. But one of these monsters is another floor 30 boss, except it's the special variant that only appears in postgame content. As far as I can tell, the only difference is that it's a different color and wears armor that falls off as we fight. My sword calls down lightning on every enemy I hit. Each time I dark souls roll to refresh my shield, I also attack enemies around me four times, also triggering lightning. Every enemy who touches me triggers a shockwave that debuffs their defence. My two companions do virtually no damage because I'm not a summoner build, but they use their incredibly flashy attacks on my GPU anyway. They're there for moral support, to look cute, and give me a small +2 to intelligence. My FPS, normally a stable 120, dips into the 40s. I take a moment of silence for the one companion who died in the fighting, but she'll respawn in 6 minutes. My other companion seems to have glitched out during the fighting and is constantly using his ultimate attack, ignoring cooldowns. It still does no damage. I sift through the 20 or so items on the floor and wish we had a loot filter. Absolutely nothing of value dropped. The trope of japanese gamers grinding forever for an item with a 2% droprate is not exaggeration, it's reality. A weapon not only has to drop at yellow rarity, it needs to have the highest upgrade potential (randomized), have three good bonus stats (also randomized), and be a base type that is actually useful and not junk like "old staff" or "worn sword". None of these attributes can be rerolled or recrafted, it just has to drop perfect. There's an achievement for reaching floor 500 in Endless Mode, and the game promises better drop rates at higher floors, but I don't know if I'm enough of a gamer for 300+ more floors of this. (The story ends at floor 51 if you're wondering.) Rustil is one of the old japanese dungeon/tower crawler roguelikes, but as an action RPG and with some modern features (free cosmetics!!). It feels very nostalgic for me, despite being a completely original game. But I think that also means I'm overlooking some rough spots that you might be so forgiving of, like the inventory management or lack of difficulty options. (This game has only really challenged me once, and that was when the legally-distinct Gundam zoned me relentlessly) If you've been a sleeper agent for the last decade and your trigger words are "Azure Dreams", "Chocobo Dungeon", or "Dark Cloud", then I can recommend this game to you. There's a special place in Hell for cats who can steal entire stacks of scrolls or potions from you in a single hit, but at least there's a merchant at home who will sell stolen items back to you.
Don’t sleep on this one. Rustil: Eternal Labyrinth Castle is the best action roguelike out there. Why? Because underneath its pretty accessible and intuitive surface, is a ridiculously robust action game with a dash of mystery dungeon roguelike flavoring, crazy monster summoning systems, highly interactive combat mechanics, and buttery smooth Gundam Extreme Vs inspired combat and movement. Action Roguelikes have always struggled with the balance of having a player kit that at a base level feels fleshed out and not shallow, while also maintaining the fact that the player kit also has to be a highly malleable blank canvas that can be heavily augmented with upgrades. Rustil is fantastic because it straddles this line excellently. This is because at their core, the three weapon types in Rustil actually have quite a bit of nuance. For instance, the sword special functions like a tethered grapple. It works as a gap closer attack that pulls you to the enemy with a quick press of the button. However, if you hold the input instead, you can grapple the enemy to pull them to you (even large enemies). In this way, the action can be used in a manner similar to Nero’s devil bringer arm from Devil May Cry or Ninja Gaiden’s flying swallow. The bayonet special gives you a projectile focused combo string that you can freely insert and mix and match with your basic combo. If you hold the input while walking or sprinting, you’ll be able to move and rapidly shoot enemies. You’re also able to seamlessly cancel into this mobile shooting state in the middle of your combos by just holding the special button in the middle of them and pressing forward on the analog stick (It’s these granular levels of action design polish that really push this game to another level). The magic staff is a high mobility weapon that has a special that’s augmented by your mobility options. The special on its own only does small beam blasts, however if used after performing a dodge or jump, it allows you to glide across the ground performing a projectile combo. To add onto this, if you perform a jump attack and then press the special button while mid-air, you’ll perform a unique and powerful projectile spin attack. This weapon is full of Gundam Extreme Vs flair and fluidity and it’s a delight. Utilizing the unique weapon functions (which also include weapon skill abilities mind you) in conjunction with Rustil’s flexible core kit that already features jump attacks, perfect dodges that recover stamina, perfect guards that stagger even the biggest of foes, as well as dodge jumps and sprint jumps that travel farther, provides a strong canvas to start from. And the best part about this, is that the core of the game also expands as the roguelike elements do. Through the metaprogression system, you’ll unlock the ability to swap between up to six different weapons at a time and twelve weapon skills in total. And this is especially interesting since a lot of the better weapons have different properties. You’ll find swords that specialize in rapid attacks, staffs that can use weapon skill abilities typically exclusive to swords, bayonets that give you more forms of currency, shields that can shoot fire in a spread like a shotgun when guarding, swords that spew magic, staffs with built in shields that nullify all damage when you’re attacking with spells, swords that do lifesteal on enemies, etc. It’s crazy and has a ton of tools to play with if you’re so inclined. And the rabbit hole only goes deeper, since the roguelike upgrades meaningfully change gameplay in significant ways. For example, one of the basic upgrades you’ll be able to find in the beginning is an upgrade called “Rising Spin”. It’s an upgrade that makes it so whenever you jump, an area of effect attack on the ground happens. In most action roguelite games, this would be a pretty lame upgrade. No big deal. However, in this game, what they don’t actually tell you is that the area of effect attack from the upgrade isn’t just damage, it also has a launcher property. So effectively, this seemingly simple upgrade turns your basic jump into a launcher that lifts enemies into the air and opens them up for aerial combos. It’s this kind of subtle action game design flourish that really puts in perspective that this was crafted by someone that loves and understands games like this extremely well. And the game is full of stuff like this. Roguelite upgrades are added to the pool as you progress the initial story run, with the upgrades themselves being handled in a similar manner to Hades where the different heroes you receive upgrades from are all focused on different aspects of the game (defense, magic support, summoning, etc.). They run the gamut of turning you into a summoning behemoth that’s able to turn enemies killed into allies, giving you a Ninja Gaiden/Shinobi-esque wall run if you jump or sword grapple onto a wall, giving your magical special attacks charged moves, giving you a huge attack buff after perfect dodging, giving you a double jump, turning your basic dodge roll into a faster quick step, turning your additional weapons into autonomously attacking drones like they’re funnels from Gundam, turning your dodge into a multihit area of effect attack, making it so your summons get significantly faster and more powerful when you’re guarding, making it so guarding with shields fires off magic bullets that reduce enemy defense, and more. It’s easy to see how a lot of these combinations can spiral into crazy synergies and builds, especially once you start factoring in that the different gear also have different unique skills associated with them and that you can capture, summon, and enhance all enemies and bosses to assist you. The game is also very accommodating for different skill levels. You can go in on Safe mode and slowly accrue a powerful arsenal that will steadily be enhanced, or you can do challenge mode and get a more authentic roguelike experience (I personally take it a step further and do the self-imposed challenge of just entering the dungeon with nothing every single time, very rewarding and well balanced way of doing things and the game even supports this playstyle with stuff like Survival mode after beating the game). But simply put, Rustil: Eternal Labyrinth Castle is spectacular. It’s delightfully interactive and a dream blend of the kind of meticulous action design you get out of a Team Ninja, Platinum Games, or Capcom title while using the full force of the mystery dungeon roguelike genre to propel it to new and exciting directions.

For the TLDR crowd: Don't agree with mixed, I recommend it to anyone who enjoys rogue-likes and action games. It has both. Yes as of 1.0.4 performance issues persist, but the performance issues clearly hasn't made it "unplayable" given my and others playtimes. You like roguelike? Play. 'Nuff said for the low attention span ones. Bit longer: Unimportant but important to note, I've played since 1.0.1. Certain issues had been fixed, most still haven't by 1.0.4, but I still had a blast. I don't agree with mixed reviews because my only gripes with it are certain traps but that's a humongous skill issue on my end and the sudden difficulty curve in stage 4 going skybound and then back... down by stage 5? But I and others made it past the story mode so what do you want me to say? I ♥♥♥♥♥♥' loved every second of it. As always, I am forced to sort by "over 10h playtime" because beyond that I only see absolute stinkers and people who actually need to learn mechanics. If I, a homunculus could learn this game and it's mechanics without a step by step guide, then so can you. Babies first roguelike? Anyways... Yes, like in the TDLR section I mentioned there are the performance issues but they're really only noticeable and even there during the "home" area. Beyond that, short hickup freeze here, short hickup freeze there but I've yet to encounter a gamebreaking one, let alone softlocking or experience ruining one. Bugs. There are plenty, but seeing the devs pumping out fixes leaves me with a big happy smile on my face. Not gonna hold them up like they're gods, but I like what I see. And I am usually needlessly critical. Anyways, the second you unlock more and more, the world opens to you. I won't keep yapping because I could for hours. This is the first game to get my attention in an amazingly good way in a decently long time. There were some, but they haven't reached this level. Why does this matter? Because I actually hate roguelikes.
Game is amazing, Never have I thought this little dungeon crawling game would be fun. Got me hooked for the past like 5 hours on this. There so many options and skill. And being able to capture bosses and use them as your companion is amazing work. Other than having a bug on your companion where they get stuck on the ground, all you have to do is re summon them on the store floor. I highly recommend this game. I can't wait for the full release of the game.
