Roll-A-Ball: Reference Gathering

For the next Roll-A-Ball/Tile Mapper game, I've decided to make a game where if you fall of the platform you die. It has twist and turns and hills and bumps that you must be able to maneuver through. I've also thought of doing a maze type Roll-A-Ball (showed in the 3rd picture). I will try to incorporate a maze into the Roll-A-Ball maps by putting up walls and dead ends of some sort.
