See i think this falls under difficult to control/unfun rather than Out of control.
Take this with a grain of salt as i have very low dexterity and these games are not great for me, but initially for the tutorial i would say instead of saying ????? for the switch sides, i would do something like [displayed at top of the screen]
secondly, i think if you added like a time slow down to the side you arent controlling then the game would flow a little nicer, other than that, the controls are really slick, and i like the core concept. with a bit more feedback to the user i think it would wound out really nicely.
