Schroden

Schroden is a puzzle platformer featuring a scientist and his ghost. You control the main character, Schroden and his ghost at the same time to solve platforming puzzles, and advance forward. While dead, Schroden can pass through objects and go places the living character can not, but can not alter the real world (eg: use buttons to open passages). If the main character dies though, then he becomes a ghost, while the ghost itself comes back to life, allowing for the "living" Schroden to get past obstacles.
