As much as I’d love as many people playing games we make as possible (and myself to be playing as many as possible) I think it would be interesting if every participant was given a random allocation of X number of games to review in these 2 weeks. That way everyone gets some feedback and that feedback may be more meaningful as each participant has a specific total to go through.
Meaningful feedback is way more important than ratings. I’d like to hope we all want to improve and make better games in future jams and meaningful feedback does a lot to aid that.
