Hey Roger, Yes, I've watched a few already. I haven't seen many of those demo's before, which bits are by you specifically? The vid "there's only one" is very cool, and that Tron demo! :O
I meant Ant Attack on the speccy, am I remembering wrong that it was a 16k game? Attributes would definately be faster, although my blitting code seems to be fairing pretty well. It plays very smoothly in 1 player mode at least. I experimented with different sizes and styles for the piece gfx and ended up really liking the 6x6. I'll upload a screen shot in a bit to show you how it looks with some pieces racked up.
