This action shoot 'em up from Japan contains blistering speed, high octane explosions and enemy bosses which fill a quarter of the screen. What's not to love?

The story fits the bill of any game of this sort - fly for no reason while billions of unnamed enemies are trying to blow you up. Fortunately, the enemies are largely weak and often help you by dropping supplies when they die.

The usual method of power-ups has been dispensed with here (a random box of goodies) and you're given the choice of three powerups, which rotate in a triangular pattern. These are shield, power and bombs.

You can either choose one power-up specifically, or fly into the center for a moment and receive all three plus bonus points. However, this may have the undesired effect of you accidentally nudging a powerup you don't specifically need at that point, so attempt this with skill.

Its pace is blistering and the enemy waves are never monotonous. Frequently ships of larger size follow a few waves of smaller, easier ships to break up any monotony. Not all of them have to be destroyed - they fly away after a set time period, which reduces any "I just have to get this last one" frustration which sometimes happens in shooters.

To summarize - it looks good. It plays well. It sounds nice. The powerup system is innovative and brings an extra level of play to the repetitious shoot, explode, wait. In short, its a very solid game which you'd do well to check out.
