This Jet Set Willy Map, I don't know if it's art but it should be:
1. Whoever made this map has screwed up the staircases.
2. Where's the rest of it? The house was much bigger than that.
3. In Jet Set Willy 2, they added a load more rooms, including several with a space theme. If you mapped them out, they formed the shape of the Starship Enterprise. (See link.)
