Ran fine, no problems.
I even accidentally left it running all day, due to the long time it took on first run preparing the shaders - it got backgrounded when my lock screen came on, and came right back up still working when I unlocked the screen hours later.
Works perfectly fine
The game starts (launcher or not) with a black screen.

Game has some performance issues but runs well on Linux without any proton-specific issues.
Game has performance issues all-around.
Due to the performance woes, would not recommend for steam deck users. Medium at 800p or 720p+FSR still does not give a stable 30fps. Would save this for another system or wait for performance fixes.

So after trying everything else I could think of, I tried the thing I should have tried first and switched back to an older version of proton. 7.0-6 ran fine on PC.

Game launches to a black screen and never advances.
Trying to launch the launcher results in an error. By switching to GE-8.16 I'm able to get the launcher to start but the game still just gives a black screen. Game is steamdeck certified but I haven't been able to get it to launch on desktop.

Past the first area, performance is a bit worse. Medium gives a stable 30fps but I doubt you'd get 60 even on low. It drops quite a bit in recon mode. Given the slow-paced gameplay, I personally don't find it detracts from the experience, and I'm finding it very fun on the Deck.

Runs on high at almost a solid 30fps but with occasional brief loading stutters. Haven't tried higher frame rates but you'd probably have to drop down to lower settings to get it consistent.
