Fight'N Rage has been update yesterday, with a bug fix, related to an incorrect enemy defeat count at end of first level (a big thanks to NattyCat for notify that bug!).
For those who are using the offline installer, I'd recommend you to update the game.

Thank you so much!

Can you look into a possible bug when running at 4k. It causes the screen to flash and the game is unplayable in full screen. It works in Window mode but it's too small to actually play

Thanks for bringing your game here, i have been enjoying it quite a bit.
Unfortunately the offline installer remains out of date (see attached image).
I have already notified a blue about it so now i am letting you know as well.
Thanks again :)

Hmm... Interesting. Gog is already who made the offline installer, maybe they need to make sure that each offline version is stable before creating the installer(?)... I must check it. Meanwhile, looks like the best way to keep it updated is using the Galaxy Client.

Offline installer is finally up to date. Thank you.
