Saved on the Wrong Board

My entry to the 2.4HoZZT contest (H126 circuit). I chose topic A: Plagiarize! The rules for that topic are as follows:

1. Before you start, import one board from any of the classic ZZT worlds.
2. Build the rest of the game around that board.

In the spirit of building the game around the stolen board, I made my game entirely from within ZZT's internal editor. You'll understand why if you play it.
