How this works: If you click on your levels, itll give you options to wether you want to reset your levels or not, every time the ball goes into the hole and you press next level, you get a level, the levels get harder depending on how many levels you have, you can delete 1x1 squares by clicking on them but this only works on 1x1 squares, you can regenerate the level without resetting your levels by clicking the button.
