It's a very solid game, a bit frustrating when all your materials collide or fall down, because you took too much time to find out in which direction your assembly line faces or place it wrong in first place. I wish you can control the assembly lines by determining the direction with the wasd keys (w = transports up, a = transports left, ...) , so you can react faster. The graphics are really good and the fact that you have good settings is stunning
