It's a lot to keep track of, difficulty on the game is higher than I intended it to be for sure. The inductors don't increase the tap BPM, just how fast your character moves along the track. The normal rings are broken up into 4/4 where each beat is 90 degrees of rotation, and the inductors change it to half time so each beat is 180 degrees; or framed another way, if you were to press each time you pass a dot, you play quarter notes on normal rings and eight notes on induced rings.
