unset SDL_VIDEODRIVER && %command%
Needed to change the launch options to be able to start the game on wayland

wont even open
Runs on my steam deck perfectly but my desktop wont even open it. I've tried every version of proton i can but no dice. Tried a few things on forums like file ownership permissions and a launch configuration i found on here. Nothing. Must just be CatchyOS

No issues
Runs perfectly well without any extra steps

Game would not launch until given permission with chmod +x ~/.steam/steamapps/common/OpusMagnum/*

unset SDL_VIDEODRIVER && %command%
On Wayland based compositors, SDL_VIDEODRIVER may be set to indicate the backend SDL should use. The game's SDL version is outdated and does not work with Wayland's native backend. So, unsetting this environment variable should force the game to run under XWayland and get it working.

No problems at all
No issues
No problem detected - Just install and play!
I just installed and played it. No complicated settings, no problems. Everything ran smoothly.
Works flawlessly out of the box!

(KDE) Switching desktops is a pain, and the in-game cursor renders outside the game in the same session.
When it "saves a gif to your Desktop" it expects a Windows path, so the shim path is actually (steam install dir)/steamapps/compatdata/558990/pfx/drive_c/users/steamuser/Desktop/
