Interpose is a well designed shooting game with good graphics and sound effects. There's not much story, but as you fly your ship through the various levels you will shoot down a variety of enemies while collecting powerups as well as money, which can be exchanged for ship upgrades in stores. You can also save your progress to load later, which is rare feature in shoot-em-up games. Overall it's a very professionally done game which is worth checking out for fans of the genre.
