I wanted give you a 5 stars, from my heart, because of the amazing music, the great gameplay, and the lovable ambiance and design. However I pointed up a bug or something in your game, mainly in level 28. Sometimes slimes off the screen get out from the platform where they're, sometimes not. It depends of your luck, and this make the game be boring.
I'm pretty sad about giving something that isn't 5. But pretty good job anyways!
