Very clever and such an interesting concept and very beautiful, well done, I found it a bit confusing at first about what to do with the buttons on the menu screen and what they meant. And I wasn't sure what the difference was between some of the blue buttons where the bird flaps its wings. Love how when you're up high there's clouds beneath. And one time I flew right through a cloud. I just couldn't get to 1000m though, highest was 999m haha.
