The game looks nice and plays really well. Those big clunky health bars could use some updates and the passing stars are a bit distracting, although they makes the game look better.
A volume option would be nice as well if this is not intended for mobile use only.
I would also pick something else than coins for the points. maybe just some glowing orbs. Coins kinda indicate you can buy something with them.
Other than that, great game :D
