Nice small game!
Handling is good, challenge interesting!
Few points you can maybe improve before adding your game on the "Game page":
- May be you can add levels? (firsts levels: big ball, big target. last levels: small ball, small targets)
- A two player mode: players are playing one after the other, the first missing the target lose the game ( and drink! :-p)
- Add some background image / character launching the ball indicating we are playing a "2D" game (For my first try, I was surprised to see gravity: I was expecting another gameplay, like Curling or something, seen by upside)
Some Ideas:
You could add a baseball player hitting the ball when the player release the power button (with a small 3-4 images animation)
Or replace the ball by an arrow and play Robinhood character!
That's just ideas to make the game even more fun!
Anyhow, nice job!
