Ohh, that makes so much more sense! Can you also delete the .git folder if you have one? That adds a lot to the size.
Surely. The whole idea is to just count what you need to see/play the game in the Godot editor. It's a shame dependancies and project files make it so complicated, but I think no one will call foul for anyone being over 2MB if they are over by an amount less than the girth of the cruft. ;-)
