I can help answer some of these questions. That said the goal of this game jam is not really a pure competition of game devs but more so a showcase of pregnancy games for the community. Yes there will be rewards for those who make exceptional games but our goal is to make it easier for people to make games as well as help inspire others to make games of their own.
1. Plugins are allowed. As Erron had mentioned previously, we will make a requirement to give credit to the plugins used for a project and that will be taken into consideration while judging. Should you wish to make your own plugins, you are welcome to do so. The idea behind plugins is that many games use them in some form or fashion and can be a core part of development. It also helps expand the base limitations of some engines as well.
2. For the possibility of a judge not being able to vote on a game, we are taking that into consideration. Likely the other judges will go over the game and possibly look at averaging in results. Our hope however is that this doesn't happen.
3. Yes, we have discussed the topic mentioned here and we will be sure to make sure all games are judged fairly and impartially.
4. I'll be honest with this question and simply say that there will be no compensation should issues arise. With that said, it is a risk you take when joining this jam. We will try however to do the best we can and come up with solutions should something we don't expect happen. You or others are welcome to contact us regarding any possible issues that happen during the jam but once the judging period is over, the results are final.
