Yeah, there's a really nice challenge with this jam at identifying and establishing scope, I've been digging these jams. My biggest issue from a personal development standpoint is hitting a bug or an issue where something isn't working, and burning time trying to fix it. My last jam took 4 hours and 33 minutes because of this. But other times it's smooth sailing, and it takes me a little under 3 hours, like some of my previous entries. Some times I don't care, so I'll go over a few minutes or 30 minutes.
I'm excited for this series of jams though, I like the idea of iterating on a project 3 times in a row and seeing how things improve each iteration.
