Thanks for the feedback. I agree that the game probably could have used some alternate controls, especially something like using 1/2/3 to control focus as an alternative to J/K/L. I'm glad you had fun and enjoyed the details with the skater animations.
The routes are randomly generated each time, and Hony procedurally increases or decreases his speed using several metrics in order to keep him moving around the screen so the player is engaged. All of his tricks and animations happen dynamically as he collides with obstacles, and rails cause him to change lanes, forcing the player to adjust camera focus.
