Yes it is true, I am insane. I have been toying the last few days with many ideas to implement a raycasting renderer in the LittleBigPlanet 2 Beta similar to the ones in games like Wolfenstein 3D or Ken's Labyrinth. Of course I don't know if I'm insane enough to implement texture mapping, I think I'd settle for at least differently colored walls.

This is not using any glitches (eg. 50 layer glitch) to accomplish its goal and of course would allow full movement on the horizontal plane. I am attempting to raise the resolution but so far my efforts result in catastrophe, the game hates it. I'm still going to try to at least get a better video up.
