You are an Electronide(El) atom, which is hungry for electrons and will absorb them every time 5 of them are accumulated. You can move around with the arrow keys, but be careful! The movement is really fast, and you bounce off walls, making it easy to accidentally hit an E666.
The Giveawaydium(Gw) atom has only one electron and wants to lose it. Just by getting close to it, you'll take the electron away and the Gw will disappear.
Eviltrisixium(E666) spawns from the almighty black hole of evilness every time you absorb electrons. As you might have guessed, it explodes when you touch it, and it's game over!
Try to beat level 15!
Also, it has nothing to do with real chemistry. AT ALL.
