It won't load for me. I'm getting the following error: Uncaught (in promise) ReferenceError: SharedArrayBuffer is not defined.
I'm guessing that you are using Godot's threaded template for html5 export. Make sure you have Newgrounds SharedArrayBuffer setting on (https://www.newgrounds.com/bbs/topic/1476758) if you really need threads. If you don't need threads, I'd make sure to set single threading in the project settings and such and export using the regular template.
I had trouble earlier with the setting on Newgrounds, so that is what I had to do to get it working.
Could just be my browser though.
Edit: Update: Work now! Cool game!
