Yeah, thats a fail.
Well, ok, it needs work. The controls take forever to respond, the sound sucks and the graphics were ok. Build from the base up. Start with the controls, make 'em smooth and responsive, then work on the graphics to make it look good. The sound needs a serious overhaul. The gun firing sounded like little kids playing with toy guns. Don't be afriad to ask for help. The fact that you got this up here at all is note worthy. Newgrounds has a huge base to help guys like you out, take a peek in the forums and ask for some help in the programing, and audio-visual departments. There are lots of sound effect websites out there, it may take time to find what you need but you'll get better responses to your efforts for your time spent looking at what is out there.
Now, I put this in most of my reviews, but don't get discouraged because of bad reviews. If you can't take negitive critism then don't do the work. You get the potential to do it well, so take heart and give it another go. Take your time, you got all the time in the world to do it right.
