Desktop: jump with ↑ / Space / W. Mobile: tap to jump. You have 3 HP: collisions deal real damage and a run ends at 0 (true fail state). Coyote-time + jump buffering keep controls fair, checkpoint floors save progress every 15s, and AI mode uses the exact same movement/collision rules as human mode.
