The first jam allowed ratings but people didn't seem to be too into it, so I stopped using that feature - I'd be open to reconsidering that if there is interest in judging. However, I think the casual nature of the jams is part of what makes them fun, and I wonder if judging would add too much pressure. But maybe there's another way to give people recognition for their games? I'm open to any ideas you have!
Also, I totally agree the community is what makes Bitsy fun! thanks for being part of it :^)
