i'd recommend removing the margin on the camera for the up and down movement and making sure that at least one platform for progression always fits within the camera limits. alternatively if you really want to keep the margin, just move the camera back to center if the player stands still for a second or turns around. for controlling the camera on keyboard i'd recommend crouching moving the camera further down after you hold it for a second, same with holding up. nine sols recently released and had a great solution to this too, which was that you had a small robot that could fly that you use to scout the areas ahead of you but that's obviously a more involved solution to make especially in a jam. i'm looking forward to seeing what you make next year if you decide to participate again!
