Hello caramelcode, I finally pushed all the content onto GitHub! It was all art and sound.
I ended up not coding, but please let me know if there is something I still need to push that I am unaware of!
It seems there is no easy solution online for the current HTML build- it will probably take me a day or two to try to make it work.
The main problem is that the HTML5/UE4Game.asm.js is too large.
