Bit.Trip CORE is the second in a six-part series of games devoted to exploding your brain. Through a mix of Atari-era aesthetics, chip-tune music, and rhythm-based gameplay that will have you crying for mercy, Gaijin Games has created the best new franchise on the WiiWare service. The first game, BEAT, updated the classic Pong mechanic of positioning a paddle in order to repel incoming balls, here called “beats.” Each subsequent hit would add a tone to the increasingly complex music. You controlled the paddle by tilting your Wii-mote forward and backward. It was a thrilling new type of retro gameplay.
