I think if everyone here was a full-time indie developer, there would be a much smaller crowd. Indie developer can mean many things, but a lot of the time to be successful it means putting a hold on side-projects and working on the project that pays (assuming you don't make money from something like YouTube showing off side-projects). Jams like this are mostly designed to incorporate everyone who loves game development, but maybe doesn't have as much time. I would't worry! Besides, a good point was made that the best games from these art-pack videos are the ones that are made in the shortest amount of time. Just a simple and fun concept stretched out as much as possible. If someone makes a game that was done in more than the time limit, it's usually painfully obvious.
