A Game Jam project, developed in a couple of hours, designed to be controlled with a Makey Makey kit.
You control a green sphere on a pitch-dark maze. You can activate a sonar (mouse click) to get a hint about your surroundings and you can move in four directions (arrow keys). You have 120s to find the exit.
Using a MakeyMakey Kit, map the controls to something more interesting. I suggest mapping the mouse click to something that makes a bell-like noise when you tap it (since it works as a sonar), and the arrow keys to something whacky just for the fun of it. During the Wooga Game Jam, I've mapped the sonar to a metallic bottle and the arrow keys to slices of lemon. We had some good laughs. Here's a Picture of my version of the controls.
