I'm not taking part of this Jam because I won't be home for some time, but I have done two jams so far, the last two weeks (Weekly game jams) and I really liked the experience, because I really takes you out of your comfort zone and forces you to start working on things and stop overthinking every little aspect of your game. And sometimes you think a feature will be easy to implement but when you get to work, you realize that thing will take you a couple of hours instead of minutes and I really like that feeling. Also the theme limitation is amazing because you make games about things that you never thought you'd make.
I'm just really happy that I'm able to join a game jam and have a product at the end of the week or after just a couple of days.

Have a nice day!
