A wonderful and fresh take on co-op games. Reminds me faintly of Guns of Icarus in 2-D. Everytime someone says they haven't played it, I make sure they've given it a shot. Still have never had someone that doesn't enjoy the game. A couple downsides include no online co-op and a less-satisfying-than-multiplayer single player mode. While the lack of online co-op may turn some away, if there is anyone you enjoys any kind of co-op game, this is THE one to try.
