Thank you again! I haven't thought about the progress regressing over time, it could be the potential fix. But as you said, this is just a 2 day jam game which I'm not really willing to put more time into. Not right now at least.
And yeah, I was planning to take part in the Godot Wild Jam, but I was traveling until now and don't think I have the mental energy for it! Similarly next month I'm also traveling during the jam period... but I plan to participate in the one after that in November :) and you?
