Bram De Moor, one of my coworkers, has developed a small game which is a part of a university study. I can't tell you what the study is about, since that would ruin the purpose of the game (and if anyone leaves a comment mentioning it, it will be deleted) but it's pretty interesting. The game itself is pretty nicely done, though you obviously shouldn't expect too much. So if you can spare about 15 minutes and want to participate in this study, download the game here, play it and answer the questionnaire at the end. Don't do it for yourself, do it for science!
