Use the arrow keys to move your green character around - your blue buddy will follow along, all the time orbiting your character. Both you (green) and your buddy (blue) can collect the packages that come from the left, but a score bonus is given for any that are collected by your buddy rather than yourself!

Any enemies (red) that are hit will reduce your score and add time to your lag meter. The amount shown on the lag meter affects how far behind your buddy follows your movements, so plan ahead to gain the bonuses!
