Simple yet solid game, pretty fun for a while, automation is really strong in this, but having to upgrade every single crawler, furnace and robots made it kinda bad at some point. Also the max of 1000 currency exchange is also bad, you can click on it and hold enter but not having an exchange all or max is bad specially when you are supposed to gather 250.000 and 1.000.000 of inteligence currency. But other than that a small yet fun game.
