Works out of the box
Did a handful of runs. Didn't do anything to make it run. Just enabled Steam Play then installed this game, and then run it.
Runs without any issues

works perfectly, aside from an easily fixable fullscreen issue
When the game was started in fullscreen, 3/4 of the scrren were black. Easy fix: maximise the game while it's starting (while the blobfish logo appears)

This is an update to my original report. I don't know if the 3/4 blackscreen-problem persists, because this issue never reappeared after exiting and reentering fullscreen via settings. However, the initial performance issues are gone now. I don't know why, as I have not played for a few weeks, but among other things I upgraded Nobara from 40 to 41. Now it runs like a charm with 60 FPS, no problems what so ever.

Whenever I wanted to play something quick on the deck, I always came back to this game. It runs flawless at 60 fps without any tinkering. I can even play it for 6h straight on battery if I wanted to, without making any optimizations (LCD deck here). This is definitely a good pick for the deck!
Great! No issues
Runs just as good as it did on Windows. Download, press play, there you go.

Second-long freeze sometimes happens (Some even make the OS totally unresponsive, requiring reboot). Typically happens in the menus/shop. (Only tested on multiplayer setting)

This was just an initial problem (3/4 black), when exiting fullscreen and entering again, it worked
The game runs horrible (30-40 fps) from wave 1. Neither the CPU nor the GPU have a load above 30% while playing. I noticed it runs way better when CLOSING both FIREFOX and DISCORD, but I mostly play with my sister over discord so this is rarely an option.
Game is very fun, but for me not playable when I want to talk to friends and family :(

crashed before it could save the round
crashes after every round
Launching in Fullscreen left 3/4 of my Screen black. Only in the upper left quarter the game was visible, but only the lower left part (1/4) of it. Works fine when selecting window mode through Nobaras taskbar. Right-clicking icon-> more -> unselect fullscreen

game-performance %command% -m -f
Tested local mulitplayers using two methods. 1) 2 controllers connected on same PC; 2) via Steam "Remote play together" function on 2 PCs. No issues being the host or guest.
Must use command option "-m -f", otherwise screen rendering got cut off and only show a small portion of the screen/menu.
Blobfish logo popped up for a split second, then crashed.
Even works on my hacked Chromebook that runs Debian.

-m -f
Launch command to fix full screen issue: -m -f Running in Wayland.

Difficulté pour aggrandir la fenêtre juste avant le lancement du jeu, bon entrainement pour le jeu.
Nécessité d'agrandir la splash windows de lancement du jeu qui apparaît durant une seconde pour que le jeu s'affiche correctement en plein écran. (C'est la partie la plus difficile à effectuer, il faut anticiper le positionnement exact de la cellule d'agrandissement de la fenêtre pour cliquer dessus au bon moment.)
Nécessite l'agrandissement de la fenêtre splash de lancement du jeu qui apparait durant 1 seconde pour que le jeu s'affiche correctement. (Nécessite le prépositionnement de la souris sur l'îcone d'agrandissement de la fenêtre pour cliquer dessus au bon moment.)

funciona 100%

While the game lunch ok in x11 env, it has issue initializing in wayland. The fullscreen only display a subset of the image. To workaround i use additionnal parameter -m -f to force it in fullscreen and it most of the time work (at worst a few restart of the game and it work).
trying to workaround in wayland the fullscreen init, using other mode to run it in compatibility mode it could break the remote play together.

Great performance, verified + platinum for a good reason

Switched to Proton Experimental
After install by Heroic Launcher and clicking PLAY nothing happened, then switched from Proton 9 to Experimental and instantly works, no issues, stable.

It seems I can workaround the 3/4 blackscreen issue by maximizing the window when initial logo page pops up. Works great afterwards.
also tried intel iGPU which has no issue.

with proton 9 and experimental, 3/4 of the screen are black and un-playable.
Switching to proton 8 used to work but stop working today after game updates. There are errors in log not appear with proton 9/experimental

3/4 of the screen was black; switching to an older proton version resolved the issue.

3/4 of screen was black

Works very well, out of the box.

use window manager script to override window properties.
Likely NVIDIA only issue, I had 3/4 black squares when using Vulkan.
It's fixed after forcing properties of my desktop resolution on window manager for brotato and fullscreen did work.
Can also be fixed with gamescope but according to my observations, gamescope is terribly laggy with Nvidia.

3/4 of screen was black, this launch options fix it, perfectly playable.

Partialy works to the Mainmenu
I see that the game has launched an I can manuver within the game with my keyboard. But it is in the top left corner and 3/4 of the screen is black. So it isn't playable and it seems like the menu isn't really working as well.
