First of all a solid game concept! The game feels good to play, and really has its ups and downs. Here are things that I loved and things that I would love to see improved:
- The visuals are really interesting. The characters are cute, and is really good. I would recommend more post-processing and contrast, but that's just my personal opinion.
- The game really had a solid gameplay loop, and would love to see it more branched out.
- The game itself, I believe, is made to be difficult, but the difficulty needs to be more exponential in my opinion. It was tough right from the get-go, which I believe is a problem with "difficult" games. You need to give the player some progress first, and then and ONLY THEN, should you break their whole world apart. Games like Getting Over It, and Give Up does this really well. I believe you should make the first couple of levels easy, just so that people get used to the mechanics, just to break them from the inside later on.
- There were chaotic elements in it that I liked, but felt like the punishment for not following the rules was too high, especially in the beginning. Which didn't give me enough time to let the beauty of the visuals sink in.
- There were some visual glitches, especially when the walls becomes translucent and with translucent materials.
- The game really could use some better sound effects. For things like movement, I would love to hear minor foot step sounds (I know it was there, but it wasn't loud enough, because the bgm took over it). I recommend adding a settings for the sounds, which would allow to tone it down based on the user's convenience. I also recommending adding sound and scaling for the UI animations. Also, sound effects for fixing anomalies could be better.
Overall, the game has great potential, and in my opinion, it needs some time balancing, and more motion to it. All the best
