Very fun relaxing game. Can be played with one hand and while listening to or doing something else.
PROTON_USE_WINED3D=1 %command% -vanillaGFX
The launch settings must be put on steam for the game to show a screen.

When I first started I had a blank screen but had sound. Changes Proton versions and it worked
PROTON_USE_WINED3D=1 %command% -vanillaGFX
If you launch the game and see a black screen, you will have to set the launch options as listed above.
Using the trackpads on the Deck is a little finnicky, but doesn't ruin the experience
PROTON_USE_WINED3D=1 %command% -vanillaGFX
Only works when you input the launch option suggested by the coon below. Sadly it will only work on desktop mode. I hear gamescope in the gaming mode wont render in WINE and so it work work there.
PROTON_USE_WINED3D=1 %command% -vanillaGFX
Works fine with both ProtonGE (Proton-7.0rc6-GE-1) and Proton 6.3-8 (although I played on Proton GE, a quick vanilla proton test shows that it also works). The only thing you need is this launch option, provided below by The coon (thanks to him).
option: PROTON_USE_WINED3D=1 %command% -vanillaGFX

For whatever reason this game doesn't play nice with DXVK, it runs fine using Wine's D3D though, my full launch options are: PROTON_USE_WINED3D=1 %command% -vanillaGFX
The game does not work as of the latest patch. I get a black screen with music playing with any proton(-ge) version.
Flawless install and native performance
After the Astronarch performance update with v.1.4.5, the game runs perfectly at the maximal fps of 60.
Flawless install and native performance, after game-patch v.1.4.5!
Occasional FPS drops (from capped 144 to 60 for a moment). Nothing impacting gameplay, particularly due to the auto-battling nature of the game. I have not found any noticeable performance degradation as the game goes on, as other users reported (did 3 runs back to back, reaching the last act in all of them).
Significantly low performance from stage 2 onwards!
In the first levels the game runs smoothly at 60fps. Around the second stage the performance is significantly decreased, the game feels laggy, delayed and choppy. Average performance is around 40fps.

slideshow
works fine for the first few fights, significant progressive slowdown of the game to slideshow after that, could not find any reports of this problem anywhere
