Data smile is a short 10 level game that tells a simple story about a computer.  I made the game primarily to test out The L0bster's Pocket Platformer game engine and to see if you could make a game before lunch on  a Saturday morning.  The good news is, you can. I simple game engines like Pocket Platformer because the constrain the developer to a limited amount of tools and features enabling them to focus on whats important making a interesting game.
