Playability:
Easy to understand and pick up. Not a great deal of depth but that's just fine. Makes for a great educational game.
Theme:
Interesting implementation of the theme here. Didn't expect a bird watching game and I think that's a fantastic application of "The World Is Watching".
Cleverness:
Very clever idea and would fit great as an educational game. Nice work!
Artistic Style:
Consistent and interesting throughout. You've done a good job with the closeups and the wideshots on this. Nice work.
