since previous game from amanita design - pilgrims - had linux version, i expected the new game to have native linux support too, but it has not. is it adobe-air-based again?
anyway, all a.d. games are known to be wine-friendly.
anyone tried to run it in linux?

As long as I know, the game is developed using Unity engine.

I only tried it quick but it is unity (64-bit only) and seems to run under wine. For some reason it tries to access /save and doesn't work if that fails (and it looks like it wants to put a binary config file in that directory). Making /save a symlink worked, not sure if there is some environment variable. The initial loading and first time an animation sequence started was a bit slow on my sandy bridge era laptop with integrated video and 8GB memory. I don't know how often that might happen during the game. It didn't seem to happen with the next animation sequence which is as far as I went. With a newer system I'm guessing it would just work other than the /save issue unless there are other issues later on.

Edit: I pilayed a while more (edit2: finished other than missing a few paintings). I didn't get the animation pause again, even in the same spot (edit2: can get a single slowdown or longer pause after startup at times). Scene changes pause up to 5 seconds or so and are infrequent enough not to be a big deal IMO. The worse issue, that I'm not sure if it is wine related or my GPU/drivers, is that the light cones do not show up, only the effect of light on the main character, monsters, and switches is visible. This means that it can sometimes be invisible what a switch does (in one case leading me to give up and look at a walkthrough video and see that there are supposed to be light cones, as can also be seen from the screenshots). I almost figured it out so I think many people would likely be able to figure it out without the light cones, but it isn't the game as intended and can be a bit frustrating. The one other thing I noticed is that some of the wall mini games are not visible, although there is always a push space indicator where it should be so that is a minor issue that just looks a bit odd. I'm not sure if there are other graphics issues I haven't noticed.

The GPU on this system is Intel HD Graphics 3000 that did not support DirectX 11 and so does not meet the minimum specs for the game. I'm guessing feature support might be somewhat different via wine and linux drivers but it could easily be that the light cones use features that are not easy to support without direct GPU support. So it may work with a GPU that supports DirectX 11 (after dealing with the strange /save thing).

Unity engine, 64-bits, it's perfect, all the elements are present for the realization of a Linux version.
I prefer to use my time otherwise than to make things work in Wine, but I buy a native version of Linux.
Please do it, I can't wait to play it.
Thank you Amanita Design.

Ps: I loved "Pilgrims" which works very well on Linux Mint 64-bits.

It was pointed out on the Steam forum that itch.io claims to have a Linux version now. If so, I hope it will be made available elsewhere too.

One developer said that for the Linux version:
" just wanted to explain the situation with Linux builds. At the moment, the only place you can get a native Linux build is at itch.io - unfortunately there were some recurring issues with audio (related to FMOD) we didn't manage to address, so we decided not to put the Linux build into wider distribution on Steam or GOG. "

" I understand it's not exactly convenient, but if you own a GOG version of the game, one way to play it on a Linux system would be to run the Windows version via Steam Proton (it allows non-Steam games to be run via Proton too.) Creaks seem to work very well with Proton, even on Steam Deck:) I hope that helps a bit. "

So here is the reason why we do not have Creaks on GOG: https://www.fmod.com/
And still a lack of information about: https://www.pcgamingwiki.com/wiki/Creaks
