Just uploaded a WebGL version of the game so you can play it in the browser. Not sure why I didn't do this in the first place. Unity WebGL is getting better each time I use it. On version 2017.2 my build comes out to about 7.9MB worth of data (i think it's about 5.3MB for code and 2MB for assets) and runs almost exactly the same with literally no time spent optimizing or tweaking. The game takes some time to load and gives you only a blank screen when it's loading (which is probably my fault). Definitely will not work on mobile browsers (no control scheme for it). I know it's not the same as if I coded this in Javascript, but I'm happy with it.

Oh hope it's not cheating that I uploaded this after the jam ended. There's no difference than the other versions.
