# Kye for C64: reconstructing the puzzle game's rules in 6502 assembly

> Kye for C64 ports the 1992 puzzle game to Commodore 64 in 6502 assembly. Its author inferred object-processing and magnet rules by testing the original, then implemented them alongside a parser for original Kye level files; the port documents its behavioral differences.
