an Ok game But...
dont get me wrong, your game keep me playing until i finished. you have good ideas and game itself was bit entertaining. but still game lacks few things. i really dont care a lot of Graphics because a good game with a solid gameplay and fun its better than a game with awesome graphics.
sometimes its hard to tell if that graphic its background or collision zone. i know this a flash game. but you should take the example of "hunters" Series. they have Simple graphics but easy to tell if that part its background. the game lacks few parts backgrounds.
in some point of the game i just wanted to "rush" my game because graphics dont catch my "eye" enjoying the game cuz the plain and simple backgrounds.
anyways Story and gameplay its good i dont have complaing about them. just try to pulish a bit your game and will be more entertaining and fun to play.
