Hey there, thank you for asking and playing!
There will be settings yes. Regarding resolution this one is quite harder. You see I've started development with resolutions 1280x720 - All the gameplay and menu mechanics were build based on that small resolution.
But during that time I figured out that some people will want higher resolutions so I made all the next programing steps, like positions of objects, visual novel parts, decisions - universal. Even right now all the CG are in 1920 x 1080! I just scale them down to match the window.
TL;DR: Setting definitely yes, Resolution also yes but resolution can take me some time to rewrite some of the gameplay and menu code.
In case of any more questions or feedback don't be shy to write to me!
