One of the ideas we had and I decided I wanted to make it happen and prototype it for fun, the other game we made "Lost & Found" can be played at http://ludumdare.com/compo/ludum-dare-31/?action=preview&uid=31047.

The game is about a vehicle on a harsh environment where the only way to navigate around is through the sensors on the screen. You can drive it with WASD keys.
