Magnedude was a game prototype made at the Global Game Jam in 2011. It is a physics puzzler based on magnets. You can attach your magnets to objects in the world. Magnets of the same charge would push those objects apart, while if they were opposite charges, they would pull them together. This allows you to attach boxes to walls and use them as platforms for example.
The object of the game was to get a laser from the start of the level to the end. This laser would bounce of mirrors and be blocked by object. The player had to use his magnets to not only unblock the laser, but also to traverse the level.
I was lead programmer in a group of 10 artists and 2 programmers.
