Try to escape from numerous levels each more special and terrifying than the other:

Level 0: Tutorial Level :
Everything is yellow, everything is calm, no one knows where the exit is but him. Better not meet him.

Level 1: Habitable Zone
Maybe less hard than the first one because this one doesn't like the light. But beware ! I didn't say it would be easy.

Level 2: Pipe Dreams
You're not comfortable in such a tight place and there are pipes, there are a lot of doors but we don't know where to go.

Probably one of the most dangerous and hardest levels. it won't be so hard for him to find you
