I really enjoyed this game. The art looks great and the music is really nice. I enjoyed the gameplay and welcomed all the returning birds individually (at least most of the time).
I have two small feedbacks:
1. If you are outside the building, the heads of the birds in the top row can stick outside.
2. It happened to me, that I got multiple birds with the same name. it would be nice, if, once you bought a bird with a given name, the name won't appear at the merchant again.
Having that said, both of these points are very minor and did not reduce the enjoyment at all.
Thanks for the game.
