You know, to be honest I do like the name "Project Stray".
The only problem I could see with it is the fact that it has the word project in it as that is a pretty common word in used in names of games.
I would keep the the "stray" somehow in the name for sure, as it nicely shows that your characters is lost. So, maybe "Strayed"
Great post! Would you mind if I included it in today's "best of gaming"?
Go for it!
