The game does what it was created to do, so good job on that. I played through all the levels a few times and it never felt like something wasn't working how it was supposed to. However I do have some suggestions. I feel like you were trying to go for a very simple color style, but I feel like it turned out a little too simple. Maybe adding some particles and screenshake would help. Also, the white pushy block was almost frustrating to control, because of how it felt like it slid on ice. I think with graphical improvements and more levels, this could feel quite polished.
