I've made changes to the game and release it so that I can get feedbacks on it. I'm also planing on porting this to Flash or maybe Game Maker so that it will be possible to play this game on the web, which I believe would be much more suitable.
This version also features two original soundtrack from Brandon Abley. Thanks buddy! :D
Any suggestion or advice are appreciate since I'm still new to flash or browser-based game programming in general. :)
