this is really cool, but some of these levels are incredibly tedious and the objectives/ targets are poorly explained. i love sniper games like this and there are a lot of aspects of this title that are really great, but i absolutely should not have to sit around staring at levels for 2,3 or more minutes before i have a chance at success (yes, im talking about the gaming expo level, which i must have spent a lifetime on waiting for a good shot and then missing because the dev's head wasnt even visible)
it's great that you've added more depth than most sniper games of this [caliber HAHAHAHAHHA], but i really think this goes a little too slow for my taste. you should consider giving the player some options for how complete they want the level to be, because however satisfying it is to finally get that perfect shot, it's a real drag to struggle through all the frustration and tedium.
that said, great job. im only mentioning these criticisms because i thoroughly enjoyed the game and i'd like to see more
