Get higher, pass all game levels and submit your score! That's the main aim of the addicting jumping game Alien Jumper. Use arrow keys to run left and right and spacebar to jump. Hard run allows bigger jumps. Combine big jumps in order to get more points. Bounce off the wall to increase your speed. The game is over when either time is up or you are below game field level for 3 seconds. Tip: Hold spacebar constantly down to maximize your jumping potential
