Im playing about getting a 3D style, repeating background, based around an old snes game Axlay.
See here for how it should look.
Well this is a really early demo, it seems to work (ish) but it needs a lot of work. It must be using a ton of texture memory at the moment.

So what needs doing
1. The background should be a sprite rather than 240 individual pngs, theres a bug with the sprite engine though and I cant set sprite heights.
2. Better maths for calculating the perspective ( any help.... )
3. Make it faster, not too sure how as the movement it based on the position in the array the moment
Tested on a 3GS and it ran same as simulator. That should get better though with a proper setup
