Very nice and simple! I quite enjoyed it though I have some caveats:
The good:
Very great art and presentation! Even down to the game page was really well done. Extremely simple controls that is also intuitive.
To improve:
As it stands, the core gameplay is still too simple, but I'm sure you're aware of that as well. I recommend fleshing out with a few more mechanics to make the gameplay sustain well, especially since you positioned your game as a high-score chaser.
Very neat!
