Click'n away!
I do like the lightning strike indicating the level change!
Simple enough concept, the game gets pretty repetitive quick. The only things that change are how many times you have to click the foods before they hit and how many come down? maybe make the foods act differently? Have a carrot move faster! Let the pies drift from one side of the screen to the other as it makes it's way to the ground. If you follow the advice of the previous post and have accumulating damage to the town you're trying to protect, perhaps carrots and apples will do less damage than a hotdog or pie? Hehe, throw the PSA in there that way.... sort of.
Another way to make things more interesting, instead of clicks shrinking down the food, perhaps clicks "eat" the food? And I would like to see tacos, PLEASE! :)
Good START, but definitely needs more to get all my five...
