That’s exactly what I attempted to do for the default screen filter (this can be turned on and off in the settings menu) though the effect may differ depending on the size of your maximum resolution display.
Glad you enjoyed the game as well! ❤️
Not weird at all lol (that would only enhance the effect imo)
I actually pondered the idea of including a 4:3 option at one brief point but then decided that users can probably do that kind of stuff on their own (case in point, you) without the game itself screwing with their set up or adding artificial black bars to constrain the carefully adjusted field of view settings.
