It's 100% possible using the built in tools for Pixel Streaming and the server I already have to deliver the full experience to a couple dozen players at a time through the browser so long as they have high speed internet and with zero download time, plus there are older greybox versions of every map that use cubes for everything that I could specify in place of the final maps to make the build a couple hundred MB and then use one of the current community solutions for WebGL.
Just time constraints unfortunately. Jam's over so no new builds for 2 weeks too.
