Escape From Booty Bay is built using the Enlightenment Foundation Libraries and is described as " a physics puzzle game in which players operate a cannon to stop pirates escaping from the prison. As players advance through the game levels, difficulty increases and new challenges are placed, like firing against moving targets."
With the EFL usage, Escape From Booty Bay even makes use of Enlightenment's own Physics library that was recently introduced, EPhysics.
EFL is the collection of Enlightenment libraries that make up the E17 window manager. "While their original intent was solely to support the window manager, the libraries quickly took on a life of their own, which is a contributing factor to the delays of the window manager itself. These libraries are so powerful, flexible, and easy to use that they present a strong platform on which to develop nearly any graphical application you could think of."
