I tried real hard to find a good write up on inertial/momentum scrolling but sadly I couldn't find anything (People seem to take it for granted these days).
The closest one I could find is a JavaScript library which adds that feature to websites: https://idiotwu.github.io/smooth-scrollbar/
Thanks for the help, I will look into it. I feel that most games always ignore the scroll wheel. It's a extra input that most players with a mouse already have. I could of used left and right keys instead of the scrolling but I thought it was more creative. It is difficult to account for because many people have different mouse sensitivities. That and accounting for stuff like framerate screen size is the hardest part of game design in my opinion. Maybe after the jam is over I could add a UI menu for scroll sensitivity if I am unable to get a scroll momentum to work.
