is one of the best 2D shmup available for the PC, featuring excellent sprite designs and an unparalleled use of zoom effect to create a sense of depth.
Enemies which are not on the same level as your ship can be shot at by using the X key. Hold it for a moment, then release to zap them with lightning. Press the Z and X key at the same time to activate your special attack.
The trial version can be downloaded by clicking on the link at the bottom of the page. Highly recommended.
