>>714247265 (OP)you'll be able to tell this was designed before the 3d platformer really existed as it has a few control problems future 3d platformers don't have
if you're trying to reposition yourself in a small area, your best bet is jumping and then using the stick while you're airborne to drift towards wherever you're going because mario has to physically hit a u turn to change directions
if you're playing on the pc port you should be able to make the camera less shitty but otherwise it's going to be tough to work with
