Pixel art and music are both glorious. Controls are simple but nuanced, based around controlling a formation rather than a single fighter. You've got nine pilots to beat three levels and three bosses. The levels are the same every time but the trick is to try to work out the best combination of pilots on each level to maximise your sustainability and efficiency. As each pilot has totally distinct strengths, weaknesses, weapons, and controls, this leads to far more replayability than you might expect, and there's also a pile of handicap-based challenges you can tack on. Might have liked another level or two but there's hours of entertainment here as-is.
