Game has a trailer, as well as a new version pushed that adjusted a few minor visual errors. The game will be rolling out with a few patches tweaking things in that regard, as well as also hopefully minimizing the load time.
From my experience running Godot3 HTML5 exports, for mobile Newgrounds loads faster but for desktop it's Itch.io. I'm not smart enough to tell you why, this is just observation from my experience. End of the day your best option is just making files smallest as possible regardless of platform, and by nature of this game's genera being high rez asset heavy, easier said than done.
