Normally, I wait til after a game is out of early access to review it (unless it's really bad ). But after the most recent update, I felt it would be a truly egregious sin on my part not to put in a review of this game and more importantly, the sole dev behind. Mortal Sin is an amazing game; one of my top 3 favorites in terms of Roguelikes, and certainly on it's own level as a hack n' slash. What this game does gameplay-wise is incredibly addicting and its aesthetic wins points for being unique. It's challenging, but man it's such a rush when you get the hang of it. I can pinpoint the exact moment my neurons activate every single time I walk into a room full of enemies dual-wielding two massive greatswords. The sheer multitude of weapons, classes, skills, attacks & combos this game offers is insane when you realize there's only 1 man behind the wheel of this death machine. Every class feels different enough with the weapons and skills they have access to that each run is a fresh coat of paint on an already solid structure. And now, with the recent addition of the pirate class and more range-oriented gameplay, the variety of weapons has, in my opinion, dramatically changed the game. It was fun before, but now I've completely fallen in love with the absolute tomfoolery that is the cannon . I had one run where I found an ultra-rare cannon ("ultra-rarity" on weapons usually means the weapon can powerstrike and whirlwind without charging it, aka holding the attack button) and, with the new and re-balanced skills from previous updates, had a skill (echo) that multiplied each projectile per the rank of the skill. I would run into a room, enemies would spawn, and I would literally press attack once and fire off a volley of rapid, large-sized AoE balls of death (had another skill that expanded the size of projectile attacks) and clear the encounter in seconds . I've never laughed so hard at something so busted yet so exhilarating ( And then I proceeded to get folded in the next biome because I was firing too much and the push back from several rapid shots pushed me of the side of the platform into a bottomless abyss It's not about completing the run, it's about sending a message). There was a good amount on offer here for what the game's EA price was when I got it way back when. Now with all the content the game has, at $20 bucks, I think the dev is short-changing himself. Which brings me to my next point: The sole developer behind Mortal Sin, Nikola Todorovic . If dedication and passion were some sort of supernatural entity, they've probably already taken possession of him as their avatar. The amount of work put into this game from the time I bought it (hell, even after that) to now is pretty unreal for just one guy. He's poured his heart into this game and it shows more and more with each new update that he really cares about delivering a quality game and the feedback he receives for it. One such feedback came in the form of a way for new players to get into the game without being sweats. So he goes and adds a new play-style around teaching combo inputs that show up on screen in succession and getting high scores from entering them correctly; it's like some Mavis-Beacon typing game . It's a way for new players to get a grip on the beast before it really sinks its teeth into them. What's funny is that the sweats love it too, because it's a whole different way to experience the game that isn't an easy mode , so a win with it on is still valid. These are the things I'm talking about with this dev: he hears the feedback about the learning curve for some of the less adderol-induced among us, but doesn't want to make some baby mode that no one will feel good about using. So he makes a way to teach players and improve their skill-level at the game, that doesn't remove the challenge, and is fun for everyone. That's impressive but, for Nikola Todorovic ? that's just a Tuesday afternoon. It's like you'll play Mortal Sin and think, "Oh, this is cool", but you might go to play something else for a while. And then, months later, seemingly out of nowhere (unless you're in the game's discord), the guy goes, "People have been asking for guns and prates in the game for a long time, I wasn't sure about it or how to do it, but now I've added multiple, fully-functioning ranged weapons to the game, and and a new class/play-style around them." You're like, "wait, what???", then he goes, "Oh, also, here's another update only a few weeks after the one I just released that adds a completely new alternate visual aesthetic for the game." Uhmm, excuse me sir: ]DO YOU EVER SLEEP??? Before the year is out, this guy will probably drop another bomb on us like his life depends on it (which it probably does to some degree). This is the kind of dedication that should get you pumped or jealous (but still pumped). This is the type of person that every industry needs to keep it going, not just the gaming industry. All-in-all, if you're looking for an exciting First-person Hack n' Slash-style Roguelike that's full of content, you're looking at it. There are 0 contenders and probably never will be if this guy keeps the pace he's going at. It goes on sale sometimes too in case you're on the fence but, honestly, I'd just go ahead and drop the 20 bucks for it; you won't be disappointed and you know it's going to someone who actually deserves it.

the dev basically redesigns the entire game every few months cause they just simply didn't like it, and I strive to have that much dedication.

Mortal Sin is a great game - absolutely worth the price it's at and the time you'll spend playing it. The gameplay mechanics are tight and easy to learn. Learning to be good at the game is challenging, but in an enjoyable way - not a frustrating one. The basic gameplay loop is engaging and fun. And there's plenty of variation so that things stay interesting. One important note up front is about the graphics. The description mentions how most compressed videos don't do the visuals justice, and that is 100% true. In person, the game's visuals are a dozen times more striking than they appear in many of the videos. Also, the game has a truly staggering degree of freedom in the visual settings, and even some cool alternate color palettes to unlock just for fun. If some aspect of the visuals is bad for you (distracting, confusing, etc.), I can almost guarantee there's an option in-game to fix it. Phenomenal work. The game itself is simple and fun. The number of different character classes helps ensure there'll always be more than one option available for you, no matter what your preferred playstyle is. The mechanics are tight and reasonable - never once did I feel "cheated" by the game. Every death was of my own making. I also think the limb-dismemberment system is quite fun. It really discourages just "whacking stuff" to progress. My berserker runs improved dramatically when I started to learn ways to quickly get at the legs of enemies that my giant freakin' iron-slab of a sword had already knocked their heads and arms off of. I should note that I'm not particularly GOOD at Mortal Sin. I got to the final boss once and didn't beat it. But that's just the thing... I don't really care? I'm having fun whenever I play it. I feel like I'm getting better at it too - even though I died fairly quickly at the final boss, the mere fact I got there had a sense of accomplishment to it. This game feels like a perfect example of the "easy to grasp, hard to master" ideal. The basics of combat are almost mindlessly easy to pick up - swing the pointy end at the bad things. And that basic understanding can carry you far enough into the game that you start to WANT to be better. And when that time comes, your basic understanding acts as a rock-solid foundation on which to build up skill. This isn't an easy game. This is a challenging game that wants you to fight against your own skill, not the control scheme or the strategy meta or whatever. This is a challenging game that makes it easy to enjoy the process of getting good. It feels cliche, but the only real negative I've got is that I wish there was more - more levels, more classes, more weapons, etc. It isn't like the game is lacking in any of those areas, I just really like the thing and have become greedy as a result. If anything, I'd wish for more variety in the level themes. Note the specifics there - the level themes, not the levels themselves. The room layouts promise a lot of variety and boy do they deliver. I just kinda wish there were more level options. I don't really think more than three levels (per run) would be good, I just think it'd be cool to have alternates available. Maybe a dark sewer similar to the castle but with a different ambiance, or a forest variant with snowy theming or something. But also note the caveat - if a game like this was to be lacking variety in any specific part, I'd want it to be the predominantly *visual* focused "level theming." The fact that it has a couple dozen classes and a variety of combos and build potentials is what's actually important to making the game fun, and the game focuses it's resources there accordingly. And again, this is so minor that it shouldn't be called a complaint. The game's in Early Access and yet feels like *an actual game* instead of a tech demo. That alone is a huge deal to me. That's the best recommendation I can give, I think. This is an Early Access game that is fun and complete. And yet the developer is clearly interested in polishing it up all the same. It's only going to get better with time, and I already really like it. All I have to do now is get better at the game at a faster rate than the game itself gets better as an experience. Which sounds like a lot of fun, really.

Game of all time, play it if you like waving big sword. There's other classes, but I don't know about the other classes because I was busy swinging my big sword to pay attention. This game and I are soulmates
