Tilt Tunnel

Steer a ship through a scrolling tunnel by tilting the board — no buttons. Onboard LEDs flash green on clean passes, amber on scrapes, and strobe on crashes.

Gates scroll toward a ship fixed near the bottom of the playfield. You steer only by tilting the Nano — the sketch streams accelerometer samples over BLE, and the browser maps X tilt onto the ship’s horizontal position. No keys, no buttons.

Clear a gate and the game writes a pass code; clip near the wall for a scrape; hit the wall and you lose a life. Each write becomes a short RGB pulse on the board (green / amber / crash strobe), so the controller answers the game with light even though there is no vibration motor.

Flash the Tilt Tunnel sketch (advertises Nano33-Tunnel — a different service from Tilt Catch), connect, press Play, and keep the ship in the moving gap as speed ramps up.

Goals

Steer a ship with accelerometer tilt instead of keys or buttons
Send LED feedback events from the game back over BLE
Survive a speeding tunnel as gaps get tighter
