Feral Heart

I can't log in. I know about the 'Play Game' tab update, but when I open the tab and try to log in it doesn't. I typed my username and password right, there's no message popping up saying that I have an incorrect username/password, it just refuses to log-in. I hit enter, the login-tab is still there instead of the 'keep this tab open' message. I miss this game, please help.
