After 10 years of work, this project is finally nearing completion: the first episode will be released in July! This is certainly encouraging for us, and it means that we shouldn't give up. There were already 2 big successful fanprojects: Zak McKracken Between Time and Space and Broken Sword 2.5. I hope we will be able to reach our goal as well!
P.S. By the way, perhaps we can think about releasing our game in separate chapters as well (of course, we should finish writing the full story first). This way public won't lose interest in our project during the years of development, and it would be easier to put up on the Internet.
