Really like the graphics in this one. Very cute. I missed the direction indicator for a bit. Went off on my own. Then became mega tornado and demolished the cities near by. I like the chaos. The particles help to sell all the motion.
I know I always have trouble with leaderboards in webGL games. I used microsoft's playfab. Which had a freetier. That lets you get around the api calls, but its a lot to set it up. Good luck.
Great job on this. Love the thumbnail art!
