Native build doesn't launch. Playable with Proton 7.0-6, but with a number of minor and significant headaches. Videos work correctly.
The game uses DirectInput; the Deck's controls work but are labeled as numbers and axes. Also, the triggers are not recognized at all.
In order to use the triggers, you should change their assignments in the Steam configurator from trigger inputs to left stick click/right stick click (LS/RS), then change LS and RS assignments to keyboard keys. I mapped RS to the X key (toggles the map), and LS to the R key (quick heal).
This way, all of the Deck's controls are used and all game functions are covered. You will also probably want to modify the in-game button assignments to make them more logical (e.g. change Attack to the A button and Block to the B button).
See control mapping notes
Save data is deleted when the game is uninstalled. No Steam Cloud support.
Frequent micro-stutters that usually aren't noticeable (but appear on the frame-time graph).
Game will sometimes soft-lock during the opening logos
Loading times between areas are affected by the number of active CPU threads - the more threads active, the longer each area takes to load. By default, with 8 active threads, the game is effectively unplayable.
Threads can be controlled with the PowerTools Decky plugin. Disabling SMT and setting thread count to 2 allows for full performance with reasonable load times.
Native Linux version is unplayable due to control issues. As such, the only option is to play via Proton and try different versions.

Since Linux version is unplayable I had to try multiple different Proton versions. I think 6.3-8 worked for me in the past, but today I am using 5.13-6. So it is possible that you might need to try multiple different versions.
Just be careful : I think if you played a little on 1 version and switch to a different Proton version, saves might be lost. I am not sure though.
Ah, and the last thing : I think that movie cutscenes don't work in this game. I am not sure because there is only 1 at the beginning, 1 almost at the end and 3 for different endings. But these cutscenes are available in game files in res/Movies/*.wmv The normal cutscenes work without issue.
Proton 5.13-1work but with some minor issues, cutscenes and additional content not working, minor graphic and controller issues.
PS2/PS3 controller with wrong configuration.
Cutscenes not working, game aditional art work too.
Proton version not work.
The game not work using proton, just load the screen and close. Native version is playable but with bugs in the controls and keyboard.
UnknownProton version hangs when intro video is supposed to start. Native version also unplayble, but because in-game bugs.
