I really like the interpritation of the theme, very original and creative. The tutorial was very breif and easy to understand. The artstyle is very simplistic but uses only 4 colors which looks very nice. The game looks polished especially i like the post processing effects. The game fits very well with the topic.
My only problems with the game is that i wish there were more levels, and that there was some music.
But other then that. This game is pretty great. Great job!
