And finally he let me know - proud as a peacock - yesterday evening. And indeed it is fun (read: solid procrastination!). So I gladly send it out to the world, as that is what friends do, and the more we procrastinate, the more peace we all have :-)
Whistly bird is build around the concept of Flappy Bird, but with an audio twist. You need to whistle to direct the bird in between the pipes.
The game information and download options can be found here at OceanshipGames.
So find your microphone set, get a glass of water (to use in between whistles ... I needed it) and get whistling. As a bonus: it practices the mouth movements, so it must have a linguistic or speech specialist benefit as well. But I must confess I found it hard, and I wished it had an adjusted speed for whistling responses. I simply do not seem to have a steady whistle in me (yet).
The short trailer gives the idea behind the game.
