The Factorio nerd in me adores this game. I think this is a super amazing concept for a game with so many options to expand the mechanics. The current build is fun, but feels repetitive after the first 4/5 levels. I think part of that is that the current placing controls feel a bit tedious with flip settings not saving between placed objects resulting in me having to flip a corner piece, then grab and flip another. With a few fixes though, and some new instruments sprinkled in. I could see this being a really awesome game, especially once you get up to basically recreating an orchestra.
