The original ZZT simulation runs independently of the 3D view. Walls become glyph-covered blocks; objects remain the characters you know.
Classic mode preserves grid actions with camera smoothing. Free mode moves continuously within cells and sends grid actions when crossing their edges. Timing-sensitive puzzles may differ.
Original ZZT 3.2 is the compatibility target. Super ZZT and modified engines are not supported. Compatibility across every archived world is not yet verified.
