In addition to Gamma's comment, I wanted to add that, as the Forge was my responsibility, I had a lot of trouble with how I'd originally coded the faces and the dice and stuff. Because of some issues with duplicating them (or not) when I needed to, what you saw with the Forge locking out the die after one change was due to one of those bugs, where if you selected the die a second time, it would not have the updated faces. That was found approximately five minutes before the end of the jam, and I was only barely able to upload a version with the lockout as a kind of fix. It was not fun. :P Of course, I also managed to upload an unrelated bug at the same time with a refactor I'd been doing, so we ended up having to fix that with a ticket to the admin team, because it was a showstopper at the time.
Thank you so much for the kind and thoughtful/constructive criticism. It is incredibly helpful to us, and inspiring. You may not always feel like it when giving a long response like that on the internet, but for many of us, it really does matter and really does help us try to do our best. Thanks again!
