This one was thought up the moment we played the game littleBIGplanet. My brother and I tried for four hours to make that floating hovercraft. It failed horribly. HORRIBLY!!
The reason this one was so late was all those flashy backgrounds. I got done with a couple of panels but it wasn't deadly enough. It didn't really conjure up Mac's deadly level making abilities.
Sadly the shooting spikes, apparently weren't possible.. Poor Gar..
And Mort.
