Has your reaction time in general improved since you got Bit.Trip Runner 2? Can I also assume you're a fan of the music?
I play Runner2 like I play Rock Band/Guitar Hero, it's more about planning ahead and "queuing" a series of moves in my head. The music by itself honestly doesn't do a lot for me, but the way the music integrates into gameplay definitely adds to the value. Unfortunately I'm not sure a lot of people are really playing it though, because after playing through it the first time I was like 6th on the leaderboards for total score.
