You run back and just manage to shut the door as a figure approaches from deep in the basement.
Strange, disturbed noises emanate from in there.
That was too close.
You have to find a way out, and quick! Damn the candy bag, you just want to get out alive!

You can choose the door on your left,

the door on your right,

the door on top of the staircase,

or try your luck again with the door underneath the staircase.
