I felt the controls were very difficult to handle and that the color changed far too rapidly to do much more than make split second "do I need to dodge that one?" calls. There were also some colors that were impossible to distinguish from each other (the purples). The pale magenta (as a square) is visually the same color as the darker purple (as a solid surface).
Not sure rewinding was ever all that helpful to me, but I had troubles with the controls generally, so I can't say for sure.
