(Follow [url=https://store.steampowered.com/curator/42150626-Jarl%2527s-Game-Treasury/]my curator[/url] for more reviews like this) Very short metroidvania platformer, but decent fun while it lasts. It only took me 40 minutes to finish (and I got the good ending that requires you to find 4 items) so I'd recommend to pick it up on a sale. You play as an enlarged atom created by Dr. Atominus, who is sick and needs to make a cure from an enlarged atom. Of course, you don't want to die so you run away and try to escape the laboratory! The game controls decently, your atom moves very fast and reacts instantly to your keyboard inputs, so it never feels like the controls are working against you... unlike some other indie platformers. Initially you can only run and jump, but later you will acquire a double jump, a wall jump, and a shooting skill, which are all used to enter previously inaccessible areas. Overall it's a very simple game, the like of which you might have found on Newgrounds over a decade ago, but it's pretty fun and the short length means it never gets tedious or boring. According to the achievements there are three different endings, so the game has a bit of replay val…

There's a whole host of niggling little problems with this otherwise medriocre, tiny, atari-style metroidvania. Map doesn't show your location, so it's hard to keep track of where you are. Text is BIG and takes some time to skip through. The button to read is the same button to jump, causing you to accidentally read stuff. Music is nothing to write home about but it's not the worst of its kind either. This game isn't hooking me in.

I was able to get every achievement and all 3 endings in 34 minutes. Yeah seriously. This game is so short and easy I don't really have much to say. I would say Baby's First Metroidvania, but I think this game manages to be so much easier than that. This is a Metroidvania that'd be perfect for your 2-week old unborn fetus.

Honestly pretty solid. The Double jump felt a little weird but you get used to it. The enemies also yeet you across the room when your hit which is a little annoying.

A really cute minivania. Some minor platforming challenges, some light puzzles, and bosses that you're more likely to one shot than anything else unless you arrive with love health. Not much in the way of secrets, just some optional pickups for the "secret" ending (that ironically is the one most players get and don't come back for the others, though it is definitely the "right" choice and the game outright tells you to get it) and coins which are there for no real reason (they respawn whenver you re-enter a room, along with enemies). If you [i]really[/i] care a lot for you bang for your buck, it is pretty short game (replayed once to get all endings, and even faffed around a bit hoping for a different ending) and doesn't really cross the "dollar per hour" some players expect even during sales. But if you're a Metroidvania fan and want a short and sweet experience, this will make you smile. Worse thing that can happen is you hate it and end up refunding, but I think you'll think the experience earns Pikku-a a reward for their efforts.

A mini metroidvania worth a dollar or 2 for an hour of your time. Hope the Devs release a bigger and more ambitious sequence, because this shoort one worked pretty well overall.
