This looks pretty interesting. My friends and I are working on a game in a similar vein to this one (teaching programming through gameplay) however it is a 2D platform game. If you like this sort of stuff check the project I'm working on at www.betathegame.com .

We have done workshops with kids and have footage although we aren't releasing playable demo's just yet. We are closing in on completion. No need for donations but if you like what we're doing please share!
