An open source game for the Apple II, written in 6502 assembly language. Original music transcribed from public domain scores (played with the 2-tone Electric Duet software). It's been very mind-opening to have to think about every byte of memory, learn bit twiddling tricks, design efficient data structures to fit game data on a 140KB floppy disk, etc.
