Will GOG make announcements of such releases on the front page? If not for the fact that I bought this game before already (though it miserably failed in Wine), I wouldn't have known that you just added a Linux version!

It fails to run for me however (Debian testing). It seems it can be glibc related. Here is a stack trace: http://pastie.org/9437153

Current glibc in Debian testing is 2.19. I suspect Ubuntu / Mint are using an older glibc. These kind of issues with glibc going out of sync between distros can be common.

UPDATE: It actually manages to start once in many times. It must be some race condition.

I've been playing Fist Puncher on Linux Mint 17.3 64bit. Runs great.

I really think this game got a bit of undue hate. It's pretty fun.
