Same learn a lot about Godot but more than that I learn A LOT about the art side.
I learn how to use gimp and the layers, at first I "cheated" making my animations through sprite manipulation with scripts. But I drew all the animation of the player character and that was awesome.
The sound part was just pure fun, doing weird sound in the mic selecting the best ones. And I am quite happy with the three "tracks" I composed for background music.
Like ForgottenForteana I can't wait to start a new project.
