The game is ok, but it has a lot of problems. The art is cool and cute and the music fits the art really well.
The pickaxe feels like it could have been anything else and it wouldn't have mattered. The looping counter is broken. If I click to loop and then try to jump without clicking again on the screen I restart the game. That slime at the start is unkillable. It would have been nice to have some feedback on how and when you are hitting enemies. When you speed up the camera moves too slowly.
