ah great to hear that it worked and that it was worth it! : )
I just programmed that combo in to be able to remove the settings files to go back to a fresh start. So that the player doesn't have to go search deep into their pc to find them. Also a bit of a strange key combination but that is to avoid removing your settings by accident but still easy to remember if you want to do it again.
That's a smart idea. I would suggest maybe changing the key combo to F1+F3 though, as it is still possible to accidentally hit F1+F2 with one finger. Especially if you got fat fingers like me, or if you have a cat that likes to walk across your keyboard.
A player/cat is much less likely to hit F1 and F3 at the same time, since they're not right next to each other. Just a little suggestion.
Also, amazing game!
