The tutorial should take a couple of minutes max, so I've clearly not made it clear enough for everyone to get it. Tank you for the feedback.
I recomend the Commissions launcer, since that has the automatic "watch" mode available from the start, where you choose speed and actions in a menu style,
In this version you have to clear the skill based game of an act to unlock the watch version.
If you try again: The disconect seems to come from you trying to react to the clap, you're just supposed to press in rhythm to the animation, like a Rhythm Heaven game.
