Tunnel - simple and strenuous game

I downloaded this port of the old arcade game "Tunnel" for the mac. You can check it out here

Its a really fun game, but the feature that really got me hooked was the use of the sudden motion sensor to play the game. It is real fun to pick up your laptop and start using it like a joystick (although its really strenuous on the wrist)

I would have liked the option to increase the speed to make it more challenging and a pause feature. But on the whole, a throughly enjoyable game :-)
