Serves it's purpose and then some.
It's certainly is aptly titled. The game itself is a little addictive, although not too challenging. Graphics are nice I think, I wasn't sure why another enemy was thrown in there in lvl 2 that had nothing different about him really (I thought he might be harder to take down or something, maybe he does more damage, if so, I didn't notice) and yet no new enemy was added for lvl 3. The controls can be slightly unresponsive, but not too bad, and a hit isn't scored when aiming at the neck some of the time. Overall a nice little shooter, and not simply a time-waster. More levels would be nice, as always :-)
