Comic sans!
Haha - I see you used this magic font! COMIC SANS! It rocks!
Anyway - it was a pretty simple game and looked nice but maybe add some upgrades; I'm thinking silly weapons like bazookas, long bow, rail gun, a mackerel...
And style points, more than one hit section on the birds - like head shot bonuses, clipping their wings, clean shot bonus.
And for fun why not your own Duck Hunt doggie at the bottom of the screen to collect the dead and carry off screen.
