We have adressed the tutorial situation a few times already and, if we'll update this project, we'll most likely add an interactive simple tutorial level. There sadly just wasn't enough time and we had to cramp all the information up into text :(
To put it simply, the signal messes up if the dancers are all clumped up, try building a row of dancers instead if you're willing to eventually give the game a 2nd try!
Sorry if the beginning isn't the best, but we still appreciate the review! :)
