Use arrows or WASD to move. Get energy from the mitochondria (red thingy) by touching it. Kill bad bacteria (black thingys) by running into them. Give waste from the bacteria to the vacuole by touching it (blue thingy). Watch out for the cytotoxic T cell (Green thingy). It will attack you if you don't have waste. If you have no energy, have more than 5 waste, if you run into a fellow lysosome (white thingys) or cytotoxic T cell, or if there are more than 10 bacteria you lose.
