Cute visuals! We clearly had similar ideas for our games.
At first I didn't understand the rules of the game. For example, I thought my goal was to protect the pear from the birds and that I lost points when it hit the birds (then I figured it all out by actually reading the description at the title screen :P). I would like to see some more visual cues that make it more clear that it's the birds who lose damage (maybe by making them flash in red).
