Students at Carnegie Mellon University's Entertainment Technology Center are developing a "First Person Puzzle" game built around forced perspective. The demo is really trippy.
The team of students, which calls itself Pillow Castle Games, says this is a proof-of-concept demo. It's impressively creative.
"We are deep in development of the game itself -- this tech demo is fairly old," said Pillow Castle on Reddit last night. "Unfortunately we can't talk about the future experience quite yet."
