I had fun playing this game. I like its simplistic art style and gameplay
However, the game would've benefited a lot from some music or some sound effects at least. I also found it difficult at first to figure out what each square can do
Another thing, I found a bug in the level selection menu. I have beaten the whole game but when I went back to the main menu to replay a level, only the first 2 levels were unlocked
A good game overall. Nice job!
