Matt Weise reviews Neo Contra, and thinks that:
"Neo Contra delivers a fun, violence-filled romp, but its virtues as a hardcore action game are tarnished by its hit-or-miss attempts at parody. Other developers have elevated the classic 2D shooter to a form of ballet, where memorizing bullet patterns and releasing your own perfect counter-attack is the grammar of an elegant dance. The best of these games—Ikaruga, Gradius V, Gunstar Heroes, etc.—are visual poetry when played by a master. Neo Contra shares much in common with the best of 2D shooters, notably its air-tight gameplay and wacky sense of destruction. However, most of Neo Contra's attempts to poke fun at itself fall flat, leaving a game that is basically fun but lacks the winning personality of its brothers."
Sure, that sounded a little like a single-paragraph review, but there's actually more
