Set in a very strange place... a bioreactor! 

Bio-Reactor is a vertical survival game where you take control of a microalgae cell fighting for its life inside an industrial bioreactor. Float upward through murky, chemical-filled water while collecting nutrients to grow stronger, dodging hazardous compounds that threaten to destroy you, and grabbing bursts of light from the reactor's LED walls to push yourself faster toward the top.

But surviving the climb is only half the battle. At the top of every level, a deadly bacteria boss is waiting — and the only way to defeat it is with the strength you've built along the way. Run out of nutrients and you're defenseless. Run out of time and it's over.

Every level is randomly generated, so no two runs are the same. How far can your algae cell survive?
