I've tried to play this game via HF using different accounts (from the guys who posted it in gamereplays.org)
I failed to login, sadly I can't understand chinese language; this error messege (can't copy and translate lol) appear after I try to login everytime . . .
It seems that HF is under maintenance since 11:00 2019/5/31 (UTC), and we have no idea when it will be finished. So temporarily you may not able to play on HF; I'm sorry for that.
