hit or hold the up and down arrow keys to move dave up and down the left and right keys don't do anything. try to collect 5000 points by collecting the cubes. DO NOT COLLECT THE EVIL JELLYFISH!!! THEY WILL DRAIN YOUR SCORE!!! also its easier to lose than to win because you need only - 500 to lose and 5000 to win, so good luck! (ps: you probaly will need it!)
