Overall, I think this game is quite badly made. The map is tiny and very roughly detailed. Enemies are often swarmed together around a corner which means when you go round the corner to shoot them they usually take you out straight away.
Another thing I noticed is that round two says "2th" round instead of "2nd".
A redeeming factor would be that the gun looked quite good and the compass was a nice little addition although was sometimes a little inaccurate.
I think the game needs some polishing to become any better than it is now.
