Pretty much basic platforming game.
You did succeed on the basics, the only lacking thing noticed was the camera, but as i'm awere that is a common difficulty most people have making games, so i wont bother with that. Id suggest only to make sure the character is centered on the camera and only make larger room horizontally only just to make it safe for initial applications.
and if there is any need for a vertical large room, make sure the gravity of the character are not heavy so its fall does not feel like a accelerating meteor.
