WOW THANKS SO MUCH!! I play the game recently on my windows Lap top and its great, I've also left review on steam. But now i can play on my normal computer. thank you for that!
Ah!
One of the solutions used launch options, which can be set in Steam if you right-click the game in your Library and go to Properties. If you're running the standalone game from itch though, I'm not sure how you'd do that.
Another solution was using PlayerPrefs which on Linux is stored in:
~/.config/unity3d/Matt Glanville/Switch 'N' Shoot
