Superflight

Superflight raises your score while you stay near a wall. In Superflight (GrizzlyGames, 2017), the score ticks up while you hug a wall as you glide through procedural terrain. This rewards risky proximity and skill, and gives players a reason to push their flying.

Game Maker's Toolkit contrasts it with Marvel's Spider-Man, which has no reward for getting close to buildings, and calls Superflight 'addictive'. Sunset Overdrive (Insomniac, 2014) takes a similar approach, giving style points and safety from zombies for staying above ground.

Reward the traversal behaviour you want, such as airtime or wall-hugging. Superflight shows that a scoring rule can steer how players move. Spider-Man has no fall damage, no reward for staying in the air and no reward for nearing buildings, so nothing pushes players to fly with more skill.
