Works out of the box
The arcade minigame doesn't work on ultrawide resolution.
Didn't encounter any problems except for the weirdness with the arcade minigame. But the whole game is weird.

Perfect
I haven't noticed any problems, it works smoothly.

Works out of the box.
There were occasional micro freezes the first time on new effects, as if some shader wasn't ready.

had to set "enable steam input" otherwise the PS4 controller would not work. This could be my default setting problem, but never had the issue before.
Switched to Experimental, and had no issues or crashes.

Some text is a bit small out of the gate but that's just due to the nature of the game
A very playable overall experience, did need to drop settings to low and cap at 40fps but once you do that it runs at a pretty solid framerate without any major issues. May benefit from fiddling with FSR but haven't really tried that yet
Played from beginning to end. Cutscenes also worked. Videos in the skill tree did not work, but managed without them.
Two or three crashes during full playthrough.
Each skill upgrade is supposed to show a short in-screen video, but all I saw was black. Futhermore, after playing the mini-game Space Runaway, the FPS went from 120 to 60, but it was easy to correct.
Online reviews showed me the game can also crash on Windows. Might not be a Linux problem.
