THIS RECOMMENDATION COMES WITH A FEW CAVEATS. This game is not for everyone.
I have 198% completion (out of likely 200%).

+ Palatable art style, filled with subtle animations to make the game feel more alive
+ Good music--high tempo, designed to keep you in the game
+ Controls are tight and responsive--for the most part
+ Almost all levels feel fresh and unique--contains a surprising variety of enemies in a game where they're all discs
+ Progression is easily tracked

- Story feels like an afterthought, told in brief comics with no dialogue
- Most abilities are underutilized or only useful for specific levels
- Your important abilities can feel bad to use at times
- "Mystery" aspect hinted at in the trailer is minimal
- Your success is not always in your hands, especially in the game's hardest levels

This last con about the game's most difficult levels is why I cannot recommend this game for everyone. If you're the kind of gamer who enjoys a short, satisfying experience with a little bit of dabbling in postgame, stop reading this and jump in. You can reach the normal ending in 2-3 hours, and reaching the 20-second/10-second goals can be satisfying--in some levels. But if you're a completionist, you are going to run into some of the most poorly-designed levels I have ever encountered in 25+ years of gaming.

Several levels, including the worst offender, Lobotomy, throw so many enemies at you in such egregious numbers that your path to success is often closed to you. Your skill alone will not get you through these levels--you MUST get lucky. We're not talking "purple coin challenge" hard--I spent almost twice as many hours on two levels than I spent on the rest of the levels, normal and hard, COMBINED. My eventual success on Lobotomy was strictly due to the time capsule placements basically coming up one after another in a row for the entire level--there simply isn't enough space to dash or slowly make your way through without the RNG gods blessing you. Maybe these levels (and all levels in general) would have been easier if the movement from the dash and slow abilities did not hurt you so much when used near walls; your dash ends immediately if you dash into a wall and your slow will get you stuck in a wall until you use the speed-up command or wind up with your guts coating the edge of your enemy. It's pathetic--so pathetic that I considered giving this game a negative recommendation as a whole. I noted that I did not fully complete this game because the last level, a boss rush, comes across the same way, and I'm not going to wait another several hours for my skills to be uplifted by the Disc Room gods.

Had I known what I was getting into going in, I would've put in about 5-7 hours doing most of the other challenges and left these few gross outliers be, winding up satisfied with my overall experience. Unfortunately, these same outliers have soured my time spent and left me pretty frustrated. If you're a completionist, take note: you WILL get pissed off as your fate is taken repeatedly out of your hands. But if you're looking for a fun, twitchy romp for a few hours, pick this up.
