shapez.io is a game about building factories to automate the creation and combination of shapes. Deliver the requested, increasingly complex shapes to progress within the game and unlock upgrades to speed up your factory.

Since the demand raises you will have to scale up your factory to fit the needs - Don't forget about resources though, you will have to expand in the infinite map!
