Not bad
Well let me give you some pros and cons to improve on. The game its self was quite entertaining...although I found that lack of gun sound didn't make it as good as it could be however i found the music did set tension. Also the game was rather short and pretty easy to win. So to summarize, your pros are: good concept and good game-play. Your cons to improve on are: extending your game, adding sound effects and also making levels harder. You have lots of potential and have no doubt seeing you on front page sometime in the near future. I hope my comments have been helpful for you.
