I get this request from time to time, I'll have to discuss it with my partner, but we had some scaling issues if we change the resolution. Sorry, but that might not happen.
Understandeable. Just a bonus topic, i don't know if it's a bug or a mechanic where when you have almost full the corruption bar, and when the twin sucubi catch you up, it will not appear the bar to dodge her binding attack, and i love that way bc it gives that you have to be cautious in some levels with some enemies so you don't lose the game.
