Control germ with arrows. If you run out of energy you lose. Eating a red particle increases energy by 10. Going forwards takes one energy, turning takes 0.5. Press z to view score. Click reset or r to restart. Have fun!
The high score is local, not all time. I will update it on V-1 so that you can split the germ so you have 2 controllable sprites. Please leave feedback if you played!
