I like the name Project Stray... so I'd go for a similar name: "Swerve", "Gallivant" both similar meaning... or
Or you should go for @gaming-trail suggestion: "Strayed".. I like it better than both but it doesn't seem as unique as them for a title.
Glad to find fellow Gamedev here by the way...
The reason I cant just use Stray is because there is another popular fps by the name Strafe.
