IMPORTANT NOTICE, PLEASE READ THIS BEFORE COMMENTING THAT IT IS BROKEN:
Troubleshooting (Unity WebGL is very prone to causing problems lately, so here are some tips):
-If you see a grey screen, try reloading the page.
-After that, if you see the Unity-Icon, wait a little (max 5 min) if the loading bar does not move. The file is about 10MB big, so it should not take too long, although it will very likely take significantly longer than it would with a flash game
-Tested with Firefox, it is guaranteed to work there
-If you see the loading screen and think it does not load, just let it run in the background for a while and come back a few minutes later (when the game starts, music will start playing)
Sadly, since this is the only way to build Unity Games for Web, we cannot do anything ourselves about this problem.
But we also offer standalone builds as a reward tier for our patrons among other benefits, so you will have no trouble with them!
