What is this?
This jam is about being creative with the controls of your game. Most developers are limiting themselves to the most standard and common controls: keyboard, mouse, gamepad. The aim of the jam is to try do experiment away from these standard boundaries.
So take out the duct tape, soldering iron, some spare parts, a development board (like the Arduino), old controller shells you have laying around, and make the ultimate control for your game. If you don’t feel like you’re too good with gluing things together, soldering etc, you can get creative with the things you already have.
