From the review: "Every 2D shoot-em-up needs a gimmick. R-Type had its detachable orb, Ikaruga allowed players to change colors and the Darius series had giant space fish. Grasshopper Manufacture's newest Xbox Live Arcade shooter, Sine Mora, also has a gimmick, though you might not guess what it is from the Latin title. The conceit here involves time. That's perfect; because it's about time we got another must-own 2D shooter for Microsoft's Xbox 360."
