hey sure thing!
i would have loved to have the camera not rigidly attached to the player but following in some way, as that felt a bit disorienting
other than that, i think some transitions in the platforming speed would be nice (it felt very 0 to 100)
also maybe variations on jump height/length that depend on player input
i think it would be good to look at games like hollow knight or even classics like mario bros to see what small things theyre doing to make the player feel more controlled, but as this is your first time making movement like this, i think you did very good!
