I decided to 'delay' Grey till after the contest and continue on a easier(?) game based on the iPod touch game Squareball.
I have been playing around with my small map here. I haven't made yet that you bounce of blocks, so you go trough them at the moment.
Anyway, what do you think of the speed? And I try to let the grayscale look the same as on-calc. When you don't move left or right the gray stays pretty(not so clear on the screenshot) but right away when I move left or right it starts looking less pretty. (As I tried to let wabbitemu show).
I guess it's kinda normal, because every time you move it has to draw a part of the map. I currently am moving 2 pixels right and left.
I'm currently trying to make the title menu.
