For being such a simple game, it's actually quite good.

There's basically two ships and depending on what mode you're playing you may be only operating one of them. Each ship is a different color, and you can only kill enemies that are the same color as you. As for the enemies, only the ones that are of the opposite color can kill you. This game relies heavily on teamwork. And if you play in the uber mode then you control both ships which can get rather intense on the higher levels.

If you do decide to try out the trial don't be surprised that only the movement stick actually does anything lol. I was hitting the trigger like crazy trying to blast those scorpions only to find that to defeat them you had to do it Pacman style.

That sounds pretty sweet. What kind of ships is it, space ships?

Yeah, space ships. A game like this would do well on WiiWare IMO.
