This past week I participated in a game jam called the Variety MegaJam. The goal of the jam was to create 10 games in 10 days in 10 different genres. I only completed 4 games within the time limit, but I still had a lot of fun and learned a lot. I think the primary thing I learned was that I have a hard time putting down an idea before I feel like I have adequately expressed the core of the concept. And one day is not really enough time to do that most of the time.
Anyway, if you want to download the games, they are available here.
