Score 490, i think i did pretty well. It was at times too easy. Based on other comments, i assume i had an unfair advantage by using a graphic tablet instead of a mouse :/
Loved the sweet music, the cute design, it all fit together perfectly. The bird noises can get a bit overwhelming when you move 100 birds at the same time. Maybe make it a max of 3 bird sounds, even if you select more?
The only nitpick i have is that it is sometimes difficult to tell(especially at the last level), which pan is at the foreground and which at the player-level-ground(you know, the ones that would hit a bird). Oh, and a timer to tell you, how long until a level is beat.
But that's really just nitpicking, i enjoyed the time.
