I'm guessing this has probably been done before but I'll just post this anyway :)
Basically just a game for a 8x8 LED Matrix similar to a game I made called LCD Road Runner, just avoid the walls this time. Good thing about this one is you can easily make your own level by following the guide included on the webpage below.
LED Matrix Road Runner v1.0 (10 December 2010) – Initial Release with 1 level
Instructions You control the dot and you need to avoid the walls, you can move in all directions.
