I wrote this game by myself within three weeks for the Liberated Pixel Cup coding competition between July 9 - August 1, 2012. The game uses art and music assets created during the LPC art phase. melonJS and Chipmunk-js are the game engine and physics engine respectively powering the game. It is free to play and available online right now!
While still incomplete, the game shows a lot of promise with its unique story and classic action-oriented gameplay.
It is open source (released under a dual license: MIT and GPL3) so developers are encouraged to contribute to the project, or take it and make it their own!
