Hi there dyenamix, sorry to hear that the game froze on you again. Does this happen often? I'm not sure if you want to, but you could try the demo on Steam; the desktop version is a bit more performant than the browser version.

If you don't mind telling me, do you remember where the game froze? How often does it happen? Does the game run smoothly otherwise? And if you don't mind giving me your computer's specs I'd appreciate that too. I've had a few reports of the game freezing, and it seems to be related to the browser version, but I'm not sure. It will also be useful to know if the Steam version freezes on you too. Any information could be helpful, thanks!
Again, my apologies.
