I'm really intrigued by the idea of this game, but I couldn't figure out how to get past the screen where I'm in the brain. If you post what the controls are, I would love to try it out!
You can control the worm (inside the brain) with WASD or the Arrow keys.
Use the neurons in the host animal's brain to force it to do things for you (e.g. walk). Your goal is to guide the creature to freedom! Or, to be eaten by the next creature :)
