My intention was to get the core game loop done by the end of day one, so I'd have all of day two to add content. Needless to say, that didn't happen, but at least the game has some nice tilesets.

I'm going for something that's NES-ish with the visuals - three colours plus transparency for the objects, three colours plus black for the tiles. I won't be sticking rigidly to the NES' limit of eight palettes, though.
