Tunnel Rush is a 3D arcade game that challenges you to survive as long as possible in a fast and dangerous tunnel. You must steer your spaceship through the twists and turns of the tunnel, avoiding walls and obstacles in your way. You can collect power-ups and coins to increase your speed and score, but be careful not to lose control or crash. The game will automatically adjust the difficulty level depending on your performance, so be prepared for some surprises. The game will end if you hit a wall or obstacle too many times or run out of time.
