Thanks for the feedback, I am not going to update the game any time soon because of other projects, but I can tell you some ideas I had while making it. First, I wanted to add "the rain" which would work as a time limit and loose condition (take photos of birds before the rain scares them away), also I wanted to add different types of food (attract birds of different species), and flutes (attracts birds of different colors). Finally some interactions for the birds like singing to the rythm of the music. Here are some unused assets I have:
Hopefully I can update it on the future, just not now :)
Glad you liked it...
