The main criticism with the last game jam was that it was closed access. That was a valid criticism, but it was also on purpose. We wanted to code and test the contest system in a controlled manner.
This time it's obviously open to everyone. The
prize money pool is now £40,000 - which is double the previous jam.
I understand the concern that old games can be re-entered. Obviously the fact they've worked on a game for 6 months vs your 30 days is going to be in our minds when reviewing them.. so don't worry about that.
And ultimately - don't worry, this isn't the last game jam. Treat this as a warm up if you want to.
