Yeah, it was the Linux version. I would suggest against completely removing this version, what is here is still playable and fun, but yeah include a disclaimer about the bugs.
Oh, and it technically did save, there were just some weird minor issues with the saves.
Yeah, I was a bit weirded out when I still didn't have any at level 4, but I just kept going anyway. I could imagine that some of the Perks would have helped a lot, I was really wanting that full party heal at least, but I guess they weren't really necessary! No real Game Overs until the last boss, who is supposed to be too strong to beat (yet manages to be simulataneously both overpowered and underpowered despite that).
Well I can't say for sure if something else about the boss was affected in the Linux version without first testing it, but for now I think there should be no more FUE instead of STR at the very least.
Also, I have received worse complains about the Linux version. I think it's just making the game look bad at this point.
Thank you again for the feedback.
