I use SugarCube 2.28.2
Not sure if I have anything else to add to the title. I really would not mind whatever is possible. Or is there a way to shorten the loading screen, and have most of the loading happen in a passage I can style however I like? Anyways something to make my various games a little unique would be nice.
[Update: I found a way google searching: editing the published html file. I searched "style-init-screen" and replaced:
border:24px solid transparent;border-radius:50%;border-top-color:#7f7f7f;border-bottom-color:#7f7f7f;width:100px;height:100px;
and now I have my own little icon twirling around! Quite nice.]
