I stay in rhythm, step on and off at the right time, with the right foot, but..
I only get every other one (hit - miss - hit - miss), YET..
If I do the opposite foot that you are supposed to I can get all of them right (it's extremely confusing to do it this way, can't even do the side steps right like this).
Is my game retarded, has there been some kind of.. bug?

I used to regularly play like 1 - 2 years ago and I don't remember having this issue.

Please help me.
