Very fun! It was hard to learn at first, but I ended up getting the hang of it. After I learned the mechanics, I spent about half an hour designing the perfect setup, which was really fun. One complaint I do have tho is the Underground conveyors. They are essential in pretty much any automation game, however, they are too op. They are cheaper, and faster. However, the game was overall very fun! I liked the part about discovering how to split/add elements in order to get the required materials.
9/10 Would recommend
