Distance-based sound effects with stereo panning for explosions, impacts, and pickups. Spacecraft entity with full state machine (fly-in, land, take off, fly-out), engine/synth sound loops, thruster particles, and PNG spritesheet. Moon level intro defers player spawn until ship lands. Also untrack build/ objects that were committed by mistake.
