Steer through the maze and eat opponents smaller than you. Grow in size by eating an enemy or a bus. To make your opponents shorter, you can nibble away at their tail. If your opponent is the same size as you or longer, you'll be eaten!
In order to escape the bathroom, you’ll need to figure out a series of point and click puzzles. Then, and only then, will you be able to find you way out of this room. Don’t try to simply leave through the door, either. Those lasers probably hurt.
