I started the jam with about 5 days experience in Godot and a couple of hours experience in pixel art. I learned an absolute ton about both (I still keep finding in-built godot functions for stuff I spent ages writing manually lol) and improved greatly at pixel art across the week - which is good and bad, because it meant I kept having to go back and touch up old assets to try and keep some consistency, definitely missed a few due to time and prioritising.
The main goal was quite a focused narrative study though, I was attempting to solve a problem I had been talking about with someone - specifically about forcing an emotional payoff in a very short amount of time (so with limited space for framing and groundwork) and have it feel "earned" rather than "unearned". Kind of a hard concept to explain succinctly, but think the intro sequence to Up if you've seen that, as an example of an earned emotional payoff with very little time for groundwork. This let me trial and learn a a lot about story telling techniques in video games beyond the obvious dialogue, narration etc.
Oh I also learned some stuff about using itch.io because I haven't done anything on here before! Also just game jamming in general, my only other game dev experience was a few small game jams like 10 years ago and it was quite a different experience - mostly how involved and active the community on this one was, very fun.
