I did it this way because I plan on adding couch co-op, but I always planned on making the mouse usable in singleplayer! Since you commented this, I think I know what I'll work on today if given the time. Thank you sincerely for the feedback.
Yeah, Ikr? We'll see if I'll have time for co-op before the voting period. Currently working on trajectory lines as I just enabled the mouse input for one player
