Author's note:

You are Karth Solemu, test pilot. Your world is in danger, and the only functional warship lies in your hands. What will you do? You are not a warrior, but you will fight. . . Adagio is a 2D scrolling space shoot-em-up ("shmup") with retro graphics, retro game play, and hectic action. Heavily influenced by shmups of yesteryear (such as R-Type, ThunderForce, and Gradius). Contains a fully functional level/enemy editor

Who needs pixel shaded polygons and realtime physical simulations when we can get 16-color graphics and hundreds of tiny sprites? That is what Adagio is all about.
