This mod completely disables the Steam platform interface and Steam integrations in Enter the Gungeon.
On Linux / Steam Deck, attempting to run modded Gungeon through the standard launcher script will cause Gungeon to panic that it's not being run through Steam. At best, Gungeon will restart itself with Steam integrations enabled and mods disabled. At worst, the game will crash. This mod prevents both of those things, allowing Modded Gungeon to run on Linux with fewer hacky workarounds.
If you want to play modded Gungeon on Linux without having to manually shuffle Steam integration DLLs around, this mod is for you. If you are anyone else, this mod is not for you.
Stuff Steamroller.dll in your .../steamapps/common/Enter the Gungeon/BepInEx/plugins/ in your plugins folder. If you use a mod manager, this step should happen automatically.
Now, later, whenever, I don't care, go nuts. O:
