Good stuff. Is it a Speccy? Is it an Amstrad? No, it's ... yes! Given the nature of the graphics you chose, do you think it could work in a turn-based, tile-based game? Maybe a cool multicoloured Speccy NetHack :) Eq.

I think a turn-based, tile-based game is just the right thing to do with it. It's annoying that it takes 27 interrupts to redraw the tile map, but that's all the poor machine can manage and still have enough CPU cycles left over to do anything else.
