This is probably one of the best platforms that I have played this jam. The movement feels great and the puzzles are interesting and fun. Great job!
Although the art is simple, it looks nice and clean. The way you used slightly differently colored blocks looks great, especially compared to a singular flat color.
The audio is also nice.
TLDR There is nothing particularly outstanding about your game, but you didn't miss the mark anywhere either. Your game is simply very solid overall!
I'd really appreciate it if you would have a look at my game as well, and be sure to download the smaller version :D
