Haha, really unique idea, and i love the art, but i have some points to maybe improve your game or things that could help you in future projects:
1. I noticed that you can only jump when you´re on grass. I don´t know if it´s intended like that, but just something i noticed.
2. The player is kind of left alone in the beginning, like, you don´t know what to do.
3. The music could be a bit longer, because you can clearly hear that it loops.
4. While the sound effects are funny, they get pretty annoying after some time.
Hope the feedback helped you, would be nice if you could check out my game "Square Pair" too. :)
