Thanks for the thorough feedback! This is a game that went through a LOT of conceptual revisions during development. At one point we did have plans for a stage like what you're describing where you shape the scale. In the end, though, I think the gameplay element that we felt delivered the most value was the "blackjack with extra steps" concept.
Was that the right choice? We'll have to check the history books in 40 years for the answer!
