Well, after some delay (exactly one week), the game is ready!
You can download the game from http://www.moddb.com/games/flight-of-the-strihuhn. Check out the screenshots and other info, or navigate straight to the 'downloads' section. After downloading, unzip the archive and follow the instructions in the readme (or just click Setup - next - next - next... if you can't wait any longer).
One more important note: Please do not give away the 'clue' of the survey to other people after you've played the game, and answer the questions as honestly as possible. We need as many 'good' participants as possible.
Thank you for participating, and have fun! :-)
