This is an interesting sort of shooter, in that you're playing against someone (either a friend or the computer AI). Projectiles fly into your side of the screen, and you try to shoot them so that they fly into our opponent's side of the screen (and hopefully make the kill). I think the concept is A+ but the execution is a bit lacking. The levels themselves end up not being that interesting, and I quickly grew tired of hearing the charge-up noise for bigger shots (vital when you have lots of bigger projectiles flying toward you). There was also a lot of slow-down in each version I played, which made it all less fun.

It is still pretty fun though, and I imagine would be best-enjoyed playing against a friend who was also into the genre. I'm surprised I haven't really ever noticed a newer iteration of this concept. Seems like something some indie studio really ought to go for, really polish it up and have it all play smoothly, have online tournament modes and whatnot.
