When you defeat Dr. Fetus, you get The End achievement for beating the game (specifically the Light World), but you still have to do the escape to finish the game. It was weird when I encountered it earlier, and if possible, I think it would be fitting to put that achievement at the end of the escape instead.

I guess that raises a curious question... If you quit out of the level during escape, does it still count as completed? Or does escape count towards your time?
