Thanks for reporting this. What OS and browser are you using? Are you on Linux by any chance?
I just released a fix that might resolve this issue. Would you mind giving it a try again, please? :)
Oh, that's awesome, I'm so happy to hear that. There was a bug related to the CRT shader which made it try redraw everything every frame in an infinite loop when the game didn't have "correct resolution size" which I suspect sometimes happens on some browsers or in some specific circumstances.
Thanks for reporting the issue and I'm glad it's working now. :)
