it's an alright game, loses its fun after a short while though, no replayability to speak of, would have been better if you didn't just have to use latest weapon.
Only part I had trouble on is killing the bottom person on lvl 24.
gah, level 20 is really intense but fun, so far made it to nearly the end of the 3rd wave of mixed on it, will try again later.
This is simple to play but challenging enough to stay fun, i do agree that a reset button would be nice though.
