You can move the character around with the keys Q,W,E,A,S,D, or with the numeric keypad. Alternatively,
you can use the mouse and click on the tile you'd like to move to.
Use 'U', backspace or the right mouse button to undo mistakes. The 'Esc' key (or middle mouse button)
brings up a menu from which you can restart if you get stuck.
Your goal is to break all the green tiles. You mainly do this by jumping on them. They will crack when
you land on them, and only disintegrate when you jump off. Try not to trap yourself!
During the game, you will be given hints and instructions on what to do. Use the cursor keys or click on
the arrows to scroll through the help pages. More pages will be added as you progress through the game,
as new tiles will keep appearing.
You can choose which level to attempt next from the map screen. Silver levels are ones you've cleared.
Black levels are ones you haven't completed yet, but are available to play.
There is no time limit and no real‐time element, so take as long as you like.
