nice game play, i like it, good job, really good job.
i loved, how you implemented the story telling into the game. however, maybe a tutorial, before the first "story part" and decreasing, the length of the story telling part would do be better in my opinion.
simple, but direct. nicely done. i can totally see this becoming a big game in the future, keep up the good work, looking forward for more of your stuff as i am making a "semi stealth" game, this really intrigued me, good job.
