The browser build is broken af. I have a fairly powerful computer and yes hardware accel is on and I'm using a standard, up-to-date, Chromium browser. If issues like this are common enough that you needed to try to cut people off from the start with a warning about "turning on hardware acceleration", something that isn't even the problem here, then the issue with the browser build is 100% something on your end bro. Every time I try to start the game it starts playing some music and then completely locks up EVERYTHING in the browser. All that can be seen is a gray screen that if I wait long enough becomes a screen with some buttons and a box to enter the player's name, but literally nothing on the screen can be clicked or typed into and very quickly the entire browser locks up again. Thank God I know the keyboard shortcuts to force quit a tab otherwise I'd probably have to close the entire browser down to get out of the lock. The gifs of the game look fun and while it's possible that the downloadable build is actually playable, I really don't know how much I care to risk it after witnessing how beyond broken the browser build is.
