Truely a fantastic puzzle game. Zachtronic's does it again with a new take on what is essentially parallel process puzzles. This feels more like a refinement of SpaceChem (also a fantastic game) allowing for significantly higher complexity if one wishes for it, but does not require it. Learn the keyboard shortcuts. They are usually quite intuitive. It makes building the instruction tracks much easier. My main gripe with the game comes with some missing QOL improvements, such as labeling "tracks" or the inability to copy and paste instructions. But those really are minor gripes for what is a well thought out game.
