Is it still worth playing?

Zachtronics' 2017 puzzle game, in which you are an alchemist building machines that create required products, based on The Codex of Alchemical Engineering, a Flash game Zach Barth made in 2008. The transmutation engine is a hex grid where you place mechanisms and glyphs. Mechanisms include arms that grab, drop, rotate and pivot, plus tracks for the arms to travel on. Glyphs bond and unbond elements, calcify basic elements into elemental salt and project metals into higher forms using quicksilver. Each arm follows its own instructions, and all arms run simultaneously, and an invalid state, such as atoms colliding, stops the program until you adjust it. Solutions are ranked by cycles, cost and area. Solutions are ranked on three measures and you can go back and improve a machine that already works, which is a reason to return to it today.
