Gaijin Games just posted this prototype video for Bit Trip Presents: Runner 2, Future Legend of Rhythm Alien, the sequel to its Independent Games Festival award winning action title Bit.Trip Runner, and it gives us a rare look at the game's early framework and the level editor used by the team.

You won't see the XBLA/PSN game's new backgrounds, fancy animations, or gameplay-influenced soundtrack here, but if you've played the original Runner, you should quickly recognize that this plays a lot like the first, in that you're hopping over obstacles and collecting gold bars/multipliers.

There's also a new move introduced here, the jump-slide, which will no doubt be used in various obstacles that send you back to the beginning of the stage if you're unable to master/time them perfectly. There's no word yet on when this will release, but you can follow Runner 2's development here.
