Great game with amazing presentation, visuals and music. I initially thought the switching controls would either be too disruptive or have too little impact, but they added a nice challenge and helped break up repetition.
Whilst I did like the smooth motion, I was having trouble getting the right position so I second the discrete increments Bonspi suggested (though it could just be my lack of skill). You might also want to add a warning about flashing lights on the game page just in case.
For future updates all I can ask for is more levels. Maybe increasing the difficulty by switching between controls faster and more frequently, or using different pointer shapes (e.g. three spokes rather than two).
I'll definitely be playing this game again.
