The whole time I was singing "That's Beyblade". I kept crashing into the boss on purpose hoping to take it out.
If you had a way to increase your spin speed via rapid button pressing or quick time events that were triggered by running over Mario Kart speed-up floor booster or even speed orbs that you collected on the course that would have been amazing to keep and tempo of the game!
If for some reason the top had particle effects that triggered when at top speed and a 3d model of a dragon appeared overhead, I would have lost my shit.
Overall I enjoy your game. music was great and the top concept was perfect for this game jam. My only wish is could go faster and smack the boss with my top speed.
