Awful framerates, but playable
Framerates in the game were very unstable, as high as 200fps and as low as 30fps. Changing graphic quality preset to low and resolution to 1280x720 did not help at all, so I just played at 1920x1080 with all settings maxed. I searched a lot online but found no solutions; it seems to be a common issue and may be related to custom environmental lighting effects implement by the game developer. Performance was just as bad using Proton 7.0-6, so I stuck with the native Linux version instead.
The game is playable with unstable framerates only because it is a slow-paced puzzle game. If this were just about any other genre of game I would consider it unplayable.
Game has controller support, but it is only parially implemented. Menus require mouse and keyboard, therfore not really enjoiable on Deck
Works great even on low end integrated graphics card. Slow to load/transition sometime but overall great.

(GOG version) Works good
Played GOG version with Proton 7.0-1.
You can progress without using the built-in notebook by taking screenshots or notes manually. The performance is overall good.
Framerate drops when very close to terrain/objects
Notebook doesn't seem to work, can't write in it.
Did not run natively. Did not run using Proton 5.13-4. Ran OK using Proton-5.9-GE-8-ST
