It's a cool starting idea, once you polish many things it could get running as a very fun and good-looking game. I liked that the controls are very intuitive and smooth right off the bat.
Things to point out:
- The UI crops incorrectly in the screen
- About the last point, maybe consider simplifying the information shown.
- While playing, the game had no sounds, maybe it's a browser thing, but it would be nice if you check that.
That said, good luck!
