well
I thought you did a very great job with how you animated the gun, gameplay was really cool. But it just seemed as thought that this game was incomplete. Maybe if you added ways in which you can move from one location to the next. Perhaps a score keeper part... or a time count down and display a score at the end. Have ways in which the guy can die, a health bar would be a very easy thing to add. Lots of small stuff can be added to this but it looks really cool and you've done well with the graphics.
