Hey! Sorry to hear that. What OS and browser are you using? I've tested on Windows/Edge, Windows/Chrome, Mac/Safari, and Mac/Chrome, as well as iOS.
I'm running Windows 10, and I use google chrome but the game automatically opens in Microsoft Edge (internet explorer). I'm going to try to see if I can get it to open in Chrome and see if that helps.
EDIT: Opening the game in Chrome worked. I don't know why I didn't try that in the first place. But thank you for the quick response!
