The Bit.Trip series continues its strange, out of order journey to PC and Mac. Following successful releases of the first game in the series (Beat) and the fourth (Runner), Bit.Trip Core is available today on Steam for PC and Mac. It's $9.99 alone, or $11.99 with a downloadable soundtrack.
The chronological second game in the pixelated series uses nothing but a D-pad (or, we suppose, keys to represent four directions on a D-pad), and involves deceptively simple rhythm gameplay. All you have to do is press a direction when a dot reaches the middle of the screen.
Of course, it's a Bit.Trip game, so you'll be screaming and wailing at that "simple" gameplay within a few minutes. In a fun way.
