Player-facing input signs for browser games: WASD, vehicles, flight, FPS mouse-look, and the #1 failure mode (inverted A/D). Mandatory control self-tests and a tiny test interface so you can verify A turns left before shipping. Load for ANY game with movement, steering, flying, driving, tanks, boats, mechs, drones, planes, karts, third-person follow cams — not only racing. Triggers on "controls", "WASD", "inverted", "steer", "flight", "airplane", "kart", "vehicle", "yaw", "roll", "pitch", "mouse look", "A/D".
