Very fun but buggy
1) Please add a automated next level when you win (and perhaps a you win screen)
2) going between levels will sometimes bug the game when you are still and fling mode and prevent you from moving the cursor
3) When opening the game, the window is too big for the screen in terms of height.
4) This is my opinion but please allow for different key bindings or add other key bindings. While not game breaking, it does get annoying.
