Thanks for trying it out! I have a shader pre-compile step which is why the game takes a bit to start the first time you launch it, but perhaps it’s not working sometimes for Edge.
Can you let me know if 1.) The game took a while to start the scene initially? There should be a 5-30 second load the first time you press start game 2.) If you have hardware acceleration turned on in the browser? It’s possible that the particles don’t work correctly without that.
