Flawless on Manjaro with kernel 5.10. No issues with video playback or gameplay.
Flathub version of Steam failed to launch it at all, however when I install Steam from my distro repository everything launched out of the box on Proton Experimental
Fresh take on the solitaire genre with a solid gameplay and great story
Worked out of the box with no problems.
Fresh take on the solitaire genre with a solid gameplay but with much of the storyline missing due to FMV encoding issue
Videos are not playing, but just showing "Skip" button. Thankfully the skipping is working, so it is half as bad. However, much of the appeal of the game is supposed to be the story, which is done using FMV.
As far as I understand the videos are encoded using H.264, which currently is not supported by Proton.
With that said, the developer will be looking into possible workarounds, such as re-encoding the videos using other Proton-friendly codecs (e.g. VP8):
That's interesting, we can definitely do some experiments on this once we've cleared some interim tasks and I've had my post release holiday (ping this thread if you've not heard of me by early November) :) Officially, the game doesn't support linux, but if this is relatively easy to do and helps you out, I'm happy to give it a go.

It's a solitaire game, yes, but it's also a narrative game, and right now videos aren't playing so you can't follow the story
Videos and cutscenes are not working. Nothing plays, but there's a "Skip video" button that allows normal play, you just don't get the story
