Cool Only gripe is that the secret boss is not well designed in terms of unfair difficulty and constantly stunning the character.

This game is unexpectedly really good for something I have never heard of before playing it. It's a light, simple, fun, and low-pressure adventure that is aimed at kids. But its simplicity is also probably its strongest plus, because nearly everything this game aims to do is simply done pretty well. Visuals and Story Firstly, the game is visually really good looking. It originally came out around 2004 for... Windows.... and then later the PSP and 3DS. Visually, the game actually looks similar to other really stunning games like Mega Man Legends to me. Past the actual modelling/texturing of the game, other things don't hold up as well. The game runs at 30fps, effects are sometimes too cheap or bright, a lot of sound effects are odd and the audio balancing can be off. There are also a decent bit of mistranslations. However! I believe this somehow adds to the charm of the game, so I seriously don't mind it much. The game also has (poorly) animated cutscenes with voice acting from an accomplished cast of actors and actresses. The game's story is extremely simple and pretty predictable in just about every way, which is fine. It's not trying to be anything deep. Combined with the style of humour that is kind of like a cartoon, it's clear that the game is trying to be fun rather than thought-provoking. Also, the main character Parin is cute and she has a lot of snark that makes her memorable as a character even against other video games. Gameplay This is where things get kind of weird as well. The game is an RPG, but it's also a platformer/adventure game. You have a drill that you can run around and attack with, drill through walls to find secrets, and interact with the world via elemental gear changes. The drill itself has combos that you can perform against enemies, which is in turn boosted by a really weird mechanic being the rhythm bar the top. For some reason, they decided that you can get critical hits if you attack to the beat of the song, which is shown at the top. However... most of the songs in the game are high tempo, meaning you can usually mash/ignore this entirely and do just fine. It's awkward to time otherwise. You also have a homing attack and you will need to do homing attack chains a la Sonic the Hedgehog. You also have upgrades to your moveset that gives access to (((OP))) special moves. Weirdly though, you perform these by "doing a spin" around Parin. This is probably vestigial from the original Windows version where you perhaps needed to do this with a mouse, but on a controller this means doing a 360. However... the game counts like ANYTHING as a 360 and so will make homing attack chains and movement really hard for the wrong reason. The game's UI is also really strange. You'll be pulling up some kind of overlay when you pause, which freezes the game. This is usually done to swap drill elements, which is kind of a pace breaker with how often you need to do it. It also has a pretty small inventory for an RPG, which gets annoying. One other important gameplay element is Drill Level. You gain it by hitting enemies and digging up holes, you lose it by getting hit. Drill Level increases your damage and intensity of special moves, so it's important to not take damage. Lastly, you get a lot of fun cosmetics to unlock over the course of multiple playthroughs that affect gameplay in various ways. These cosmetics are part of a broader reward system that is in place for exploring thoroughly. From desktop screensavers to outfits to abilities to weapon parts, this game really wants you to look around. And honestly, it's very well done. I'm just finding this out now, but there is even a secret unlockable character to play if you get the true ending multiple times. More on that soon... RPG...? Now on to less-than-good things. Firstly, I get it's an RPG so it gets its replay value from repeated playthroughs. But... why is it so grindy? Getting 1500+ scrap to fully upgrade a SINGLE hat in the game with most armoured enemies dropping like 5 per is crazy. The game also wants you to 100% like FIVE TIMES to get the true ending. While the other playthroughs have NG+ difficulty, new gimmicks, and a few cool changes/secrets, this is tedious. To S rank one level, you need to hit every pot, kill every enemy, and open every chest. The game WILL hide at least one of these in a clever spot, forcing meticulous backtracking. Now, do this for every level in the game. Five times. And every playthrough is 15-35 hours long. No, I don't think I will. Why The mustache NPC, Cylinder. Why bro? Maybe his lines are supposed to be a sick attempt at shock humour, but he's an older man that constantly flirts with Parin and she is 12. From his gross lines to him giving his "Sweaty Parts" to you as a drill upgrade (this is real) , it's really out of place and makes no sense in the game as NOTHING else is like it. So like, why? He alone is a legitimate demerit on the game. This combined with what happens when you use a health restoration point gives me a really odd feeling about some people behind the game. Conclusion That nastiness aside, if you want a cozy game with a classic feeling, great OST, cool bosses, and plenty of secrets (too many to count), this is a good buy. It's relatively cheap but I think it tends to go on sale. It's not perfect by any means, but I think for what it sought to do it did well. Sad there's no sequel because I really enjoyed this weird game, definitely underrated.

Played this for the first time at the ripe old age of 29 and was really captivated by it, decided to go for 100% just to play it more. If you played this game as a kid and were in the trenches telling people it's an underrated hidden gem I just wanna say you're so valid for that. Fun game with a lot of soul and a banging soundtrack.

This is a long overdue review on a game due to life reasons that I put on the backburner so to speak and restarted recently and I will say Gurumin is a silly charming game that goes in a somewhat interesting direction with it's story and has gameplay that I feel suffers for a frankly silly reason in my book that you can almost entirely ignore and just have fun with instead, which I wish I did XD but it's another great Falcom game with simple yet fun mechanics to it dood. Okay full review time! So Gurumin follows the adventures of Parin! A young missy who travelled to a miners town to live with her Grandpa, here she discovers some new friends only she can she and she begins on a unique adventure in a unique land not quite her own dood! The game plays rather basically, you have an attack, (X/A) a dodge (Square/X) and a jump...and that's it! well kiiind of, later on in the game you unlock some skills but those don't really use any more buttons to perform, oh you can also charge attack too by holding the attack button and letting the meter fill, very important dood! You have two special mechanics in this game too, first off is the critical mechanic, this isn't random and I believe tied to the music! Great coming from Falcom who are very much great with their music thanks to their in house team, you'll see stars on your charge meter, time it to the centre and you get a critical! This fills up a star icon up to 100, 99 if you're full, full of what ya ask!? Full of weapon meter! This fills up to 3 levels (and kind of a max level too) these determine what skills you can use, how much damage you do and finally at max gives you a projectile to shoot out which is very LoZ right there but handy is handy dood! Dungeons are interesting and lively no less, you go through defeating monsters, breaking jars, finding treasures and solving puzzles but this is where the game can feel kind of eh if you play it a certain way too, what way you ask? For rank! Ya see to get rank you need to kill all enemies, find all jars (trash cans and piggy banks too) and beat the level decently fast too without getting a game over to get S ranks, this gets you a gold medal which let's you buy unique accessories and depending on the difficulty outfits too, which are awesome granted but slows down the gameplay aspect, especially with how well hidden some of them are, I often found myself getting bored playing a level over and over to find a well hidden enemy or the like but that said I believe you can grind them on an easy level anyway and it's all only really in aid of an achievement which seems broken anyway? I'd suggest looking up a possible fix if you're an achievement hunter and if not just to enjoy the game for what it is dood. So I mentioned accessories and this is where it gets interesting because they not only function as a slight change of wardrobe but also have effects to them, all different ones, ranging from damage protection, increased attack power and even immunity to certain aspects of dungeons, they are fun but it does make you wish you could trade/toggle the effects between them to have a custom look, you also enhance them up to level 5 for even more effects! How? By collecting junk, lot's and lot's of it, too much honestly! But I guess level 5 isn't all that necessary really outside of a super boss and possibly hard mode dood. All in all it's a very simple game as you can probably tell, it was a PSP game I believe originally after all but between it's charm and humour it's something I feel anyone can get into, heck even young ones, that said it does have some let downs, it's NG+ is severely lacking in the plus aspect, only adding sub quests, taking all you accessories away, (thank goodness not your outfits though) all your items and coins away too, leaving you to buy everything all over again, a kind of exception being the gold coin accessories which you can buy 2 of for just 1 coin, then the other costs 28 suddenly...yeah that's real mean devs lol, there's the achievement issue I mentioned, you do however keep your money, junk and the levels of your accessories remain, (praise Adios for large mercies there) plus ya can also buy all skills right away, I mean it's all expensive so save money for round two if you plan on it dood. And that's it! For a PSP game it was a great time, if the NG+ was a little better I'd even consider playing it a second time, hopefully if you pick it up you enjoy it as much as I did, thank you for reading dood! ^-^7
