Haha yeah I always forget to set those too. Also did you use SDFs for the little background moving blobs?
Good question! I have no clue as I am "programming challenged." Though I can tell you where I got it! We grabbed it from the CC0 license section of Godot Shaders. To be more specific, we used this 2D Procedural Water shader by flytrap. I saw it used in a previous Godot Wild Jam winner and ended up using it all the time (maybe way more than I should).
