I've been working away on Primary 2 and I recently took some time to take part in the 2012 IDGA Chicago Game Jam. Several developers came together and had a good time making games together and networking.
In the end my team was chosen as the winner thanks to my experience with game jams like the ones here on Newgrounds. If you want to make games but can't you should participate in the jam however you can. It isn't about winning it is about participating.
Anyway as I said I'm working on Primary and I have a pretty solid engine but the final game is still a long way off. So I'm working on a smaller project on the side. Bringing BearBound to mobile.
I have all the ground work done and need time to do art but money is tight so I'm dong a small kickstarter for the game soon. By the way, BearBound was made for a Newgrounds Game Jam.
So even if you can't do much participate in the NG game jams you WILL learn something. And you might make a hit game by accident.
