This turned out great, but I think there's something even cooler hiding in this mechanic that you made.
Gut feeling is that it wants predesigned levels or SOME predesigned sequences (either small or long) that can allow players to anticipate (rather than just react) to the game. I think it'll give the player a sense of mastering the game (eg. DDR or Beat Saber) - but that's just a gut feeling!
