Never tried playing it on a browser but checked it out of curiosity. Overall impressive stuff and props to them for doing it, but yeah, I do get some errors with WarpPhoneText. However, it appears it's an error exclusive to the hosting site (porngameshub) or rather their version of the game. In fact, all the errors mentioned in the comments are a first to me.
You'll have to take it to the admins, I'm afraid. I did notice some minor modifications. Sabmod is installed, so I'm guessing they made some other minor tweaks too. Maybe forgot to copy some bits or maybe something broke along the way. No idea. If you don't wanna wait for their fix, then feel free to download the game. I can see you can export the saves.
