Shapez.io at Pbs games is another great .io game which is really good for relaxation. In each level, you have to deliver the requested shapes. The requirements become increasingly complex. As you proceed, you can 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! Since shapes can get boring soon you need to mix colors and paint your shapes with it. Combine red, green and blue color resources to produce different colors and paint shapes with it to satisfy the demand.
