I participated at the Global Game Jam 2013 and came up with a promising gaming idea, suitable for disabled (blind) people (and scored the “Games for Change“-badge with it as well). It’s a puzzle game, where you have to “match” musical pattern. The game is just at a prototyping-level, but in the end, you get the idea. Maybe it is possible, to put more musical drive into that idea. The game was realized in Renoise and the Renoise Lua-Scripting-Interface (which I absolutely like)! Here is the official link to this project and the Global Game Jam 2013 entry.
