Your game's art is stunning and I don't think I need to say that. The idea behind the game is really cool, but when I played it I felt it didn't reach it's fullest potential. Don't think that I didn't enjoy your game or it isn't really good, I just wanted to mention the only problem I had in you game so you can get better at gamedev.
Anyways, Your game is good, the art is amazing and I would really enjoy more complex levels.
Cheers :)
