updated to WebGL 3

so it's been a good couple of years since I worked on this, in that time frame Unity went from introducing a new GUI system, to webgl, to now starting to supporting VR, time flies! And so does my dev skill, where this was my first game I properly worked on and put online, it's nice to go back and see how far I've come in many respects.

That's pretty much it, just updating to make sure it can still be played and uses better tech/code to do some things, I'm going to do another update later this week to reduce the file size and clean up some of the animations/game feel.
