There's your problem
Never played any of the sequels. I don't want BIT.TRIP CORE, however, but RUNNER.
Yeah, RUNNER is pretty good, but really easy compared to the others because of the bit-sized levels. I think FLUX pulled it off better, with the regular level length, but checkpoints so newbies can finish the game too, but veterans still have trouble with good scores.
Speaking of that I'm so damn close to perfect the first level of FLUX. But the boss hates me
