Use the space bar or the up arrow to jump! Try to get the cube as far as possible in this endless game! See how many seconds you last before you explode! Also, press the E key if you want to switch the cube to the companion cube from portal! :) ( If you don't like the portal companion cube, you can press C to change it back - a function only available to Super Cube.:) )
