Really cool puzzle game if you're particularly good at engineering systems. It's super cool to create a production pipeline, tweak it bit by bit until it actually works, and then try to hone the design to get it as efficient as possible, which the game scores you on. Super satisfying! As you go through the campaign the story goes places and the objectives get bigger and bigger requiring bigger and bigger feats of engineering, which really puts you through your paces. It's very for me! <3
