In terms of "seeing things" it doesn't seem to get any more psychotic than this. In Crush, you'll be playing a rather disgruntled dude who's got some coo-coo feathers muddling his brain due to lack of sleep. And if you're talking about a game that concerns the inner workings of the mind, you're bound to expect some trippy gameplay.

This PSP-exclusive game from Sega will have you guys switching constantly from 3D to 2D and back again as you try to puzzle your way through every level. Changing camera angles and "crushing" your environment will eventually hit you with insomnia too. From the way we see it, this looks like a very addicting game - combining both puzzle and platformer genres.

We know descriptions of the game can't really do much. And with Crush, it really is hard to picture how it's played out. That's where this trailer comes in. It sums up just about everything you need to know to figure out how psychotic this really is.
