Very good suggestion for tracking stats - I'll try to incorporate that into a post jam version. Not sure how to make it work for webgl since it has no inherent persistent storage.
Regarding the tutorial - you are right, learning by playing is almost always better. I'm not sure how I'd convey some things without text (inverted dice and that the order on the bottom doesn't matter). Also, for a game jam I'd rather over explain than under and risk people being confused before judging it "broken" haha. I'll definitely explore some ways to do that though if I continue it.
