Not very good
The bad things:
1) No animation at all. Nothing moved.
2) Bad color scheme.
3) Bad graphics... very bad.
4) The only sound was the sound of the gun firing.
The good things:
1) It worked they way it was designed to.
2) I like the idea of only being able to see what you can see through the scope.
3) I also like how the scope got smaller each time adding a bit of difficulty.
Why did you have the chance to get bonus points when points did absolutely nothing for you? Your points aren't displayed at the end anyway... I'm not sure why points were even a part of it at all. Honestly, the thing that really killed it was the graphics.
