Hey thank you for looking it over and leaving me this feedback. Plenty of poeple have looked at it but yours is the first comment.
Can you tell me a little more about what was missing from the instructions? You say you did not understand there are several birds and you must "pan" to see them. How could I say that? Like this:
"To see the birds you must click on the frame and drag to the right. This will cause the background to scroll. You can scroll up, down, right or left. When a bird comes into view you will hear its call and see a pulsating green circle which indicates its location -- but it will be invisible at first. Try to guess what the bird is by listening to its sound, and select its name from the box in the upper right part of the screen. If you want a visual hint click on the Visual button. Each time you click it will make the bird less transparent -- but it will also take points off your score."
We plan to add a lot more features, including multiple difficulty levels (so advanced levels only show part of the bird such as just its head, the transparency is not as strong, etc), much wider worlds, animation such as rippling water and rain, many more birds, more habitats, better integration of birds in the world and so on.
Thanks again,
