[maze] light weight switch puzzle bypass

By jumping on the robot head, the girl can access the higher positionned door.
Bug similar to this one.



expecting the girl to not be able to jump on the robot's head, or the door to be higher.

This is another case where I think a bug has interesting gameplay potential if you built one or two puzzles around it. It kind of makes sense that in some situations, if this game were real life, you might need the robot's height to give the girl a boost to places neither of them could reach on their own; just something to think about.

It's fine here because the girl still need the robot to proceed. Marked as Will Not Fix.
@gwolffe Yes, I wanted that gameplay, but we didn't have to implement it; maybe in the next game.
