the game is a bit confusing to start. the eating in the birds needs to be better explained (for those that can not understand what is the requirement is, move the mouse to the top of the game screen) the towers are a bit weak, and tough to recover from when the targets get to the top. i would recommend just compressing the image so the player can see the mouth and the targets without having to scroll up and down. not a bad idea for a game, just needs a little fine tuning.
