I like the puzzle mechanic of this game. I also appreciate it killing you if you would get stuck inside of the block. However, as others have said it sometimes kills you randomly. That's not too problematic for me because it's a game jam, and you just restart the level. Unfortunately, I got stuck twice in the way pictured, and I couldn't find any way to restart a level, so I lost all progress.
Overall a nice game jam puzzle game.
