Doppelwalker: Neither Mac nor the Linux offline installers have been updated.
ERISS: Some year ago the dev studio to survive had to remove the dev supporting Linux and Mac.
The last version 525 runs well on Galaxy and Win10, I just veryfied.
Thanks for the info.
I had great time with the game when I was still using Windows 7. Sadly, the PC I had at the time was not powerful enough. The game often started getting laggy after each subsequent expedition. I still managed to push through and had a great time with the game. The Holy Grail addition took me by surprise. I think I missed 2-3 treasures from it. At one point I was so close of getting one of them, but the cat boss got me. Oh well, maybe I will consider running the Windows version via Wine instead.
