Very cool, always love reading about people's creative process. "Cookie Flicker" is such a good title, even though this game has little to do with Cookie Clicker (aside from cookies lol).
I was wondering: why the switch to Godot? I made a similar switch from Unity to Godot, though it was before I started doing game jams. For me, I made the switch because of the changes in monetization policy for using Unity. Even though they reverted those changes since, it makes it harder to justify using a piece of software when they've demonstrated they have no issue changing something as major as that at the drop of a hat.
