I don’t feel comfortable using a mouse
This is in general and not specific to any game… There exists a myriad of people who are comfortable with using mouse and keyboard while still preferring controllers for some specific games. You should try to better your reading comprehension.

Some games literally don’t use a mouse. For instance Baba Is You or The Binding Of Isaac or Shank would, at best, use the mouse for menus. You could play them exclusively with a keyboard but 1) you’re giving up analog input, and 2) unless you have a gaming keyboard, some of those games will have horrific keyboard ghosting especially if they have any sort of combos like Shank does.
