Version 3! This one lags less that any of the previous versions and has two AI players too :) - Cool! Plays much better when NOT full screen. I was asked by @Oui1024 whether I could show him how to create a game that would rotate the level dependent on where you were standing in that level. What immediately sprang to mind was Mario Galaxy... So here is a first attempt at a game engine allowing for this kind of player/world interaction.
