Ehh... needs work.
It was slow paced and repetitive. It lacked any real feeling to the game. After awhile it just got hard to see the little enemy dudes. The music and sound effects made me want to have a warshak test done while being electrocuted. Props for smooth game play.
Try some better graphics really give me something to look at. Also the sounds were bland, I mean bland like attending a lecture by Ben Stein on quantum particle wave analysis and its effects on P-Branes and stock market values. Pump it up a little, give it some fire. Find a local rock band and pay them to make you some hard core music. Turn up the weapon volume, not this little put-put-put, make it sound like we're in a cross between a Dirty Hairy movie and a Terminator movie at Imax. LOUD, ABRASIVE, AND FUN.
