The challenges and philosophies of Crush

At yesterday's Experimental Game Design lecture, Alex Butterfield discussed his latest project, the mind-bending PSP title Crush, billed as a "revolution twist on the puzzle platform."

Butterfield's presentation focus on the challenges of making a game that seemingly transitions from 2D to 3D without effort. Crush is designed so that your character, who is under hypnosis to cure insomnia and forced to find a way through 40 dream sequence levels, can only "crush" (transform 3-dimensional space into 2-dimensional platformer) horizontally and top-down.
