Stll works out of the box with Proton 7.0-3

tinkerer report because I still use proton 5.0-9
New content updates still work, and so do the newer versions of Proton!
Still works out of the box, even with the new updates and there have been no regressions with Proton 5.0.
Works perfect out of the box
Got a quite a few endings and achievements with the game so far, I doubt I'll run into any other issues running on Linux. The animations might look slow but if you watch the game's trailer that's how they're meant to look and isn't an issue with Proton.
Got a few endings, didn't encounter any issues with the game
Tried out the achievements sync and it worked without problems, got a few different endings, tried out both the Adventure and Simplified modes and made a save in all save slots. Game works perfectly with Proton!

Great out of the box experience
Tested with the new Proton 4.11-11, and it worked without any tweaks. Navigated around the main menu and briefly played the start of the game. The animations seemed low framerate but when I checked the Steam trailers for some (spoiler free) gameplay, they matched up. So it isn't a Proton issue. Great compatibility!
