Use the arrow keys or "a" and "d" to move. The O2 (Oxygen) gives you life, while the CO2 (Carbon Dioxide) gives you slowness. The earth is the score. The CO kills you (it doesn't stand for Colorado, it stands Carbon Monoxide). The O (Oxygen) gives you speed. A better way to put is, collect the non-white stuff, or the blue stuff. In the comments, tell me you're score you got. Waterflood1 and I got 850.
