works great

Game runs fine. No complaints.
Startup was a bit longer than expected; I just waited, and eventually the game launched. After launch, the game was in windowed mode despite default fullscreen settings; I just toggled to borderless fullscreen, then back, which resolved the issue.
Works out of the box
Works perfectly out of the box

Works like native.
Multiplayer worked perfectly.

No issues at all
Game does not start
The game will not start under any version of Proton that I've tried.
No Issues
Gotten to third planet so far, no issues whatsoever, even opening cinematic works.
Singleplayer mode works perfectly
Multiplayer not working
Cannot connect to multiplayer
Multiplayer mode needs 7.0-2 but that causes a crash at the first boss.
The game is consistently crashing at the first boss
Game crashing at first boss, but until then no issues
Only proton version that worked for me was 7.0-2, and even that until the first boss
Game works great except it would not detect my Xbox Elite wired controller (which works in plenty of other Proton games).

Works 100% perfect for me using Proton Experimental. Even detected my Xbox bluetooth controller and auto set up the right buttons.
Great game for playing on Linux.
PS: the game is awesome
