Main Cell

Controls: WASD - move, SPACE - jump, E - pickup items, Q - look from eyes of creature.

Using gun: LMB vacuum FOOD, SHIT and BLOOD, RMB - throw collected items.

You are a cell inside creature, and you should serve for creature well-being:
grind food(smashing pieces of food in the mouth, cause this creature is toothless), carry it into the stomach, fill special cells with oxygen from the lungs and nutrients from the stomach, carry filled cells in the heart, remove and push shit out of the creature.
And also you should protect creature from viruses and hostile bacterias.

Red Blood Cells kills  viruses and healing wounds. Use LMB being inside heart to collect blood from Heart.

There are some bugs. Sorry for it.  :(
