Details and Warehouse. Tap Details to open the Factory Building's details and/or level it up. Tap the Warehouse to check your inventory.
Order List. Tap to open the list of ongoing orders/items being created and the time it takes for them to finish. Also shows the number of Energizers needed to instantly complete an order.
The Factories. Tap any of the available factories to see the list of orders, as well as the one currently ongoing (if there is any).
Quartz Sand and Energizers. Shows the amount of Quartz Sand and Energizers the player has on hand.
Each individual Factory can create any number of materials as long as:
The player has the components available (the factory will create it alongside the item if it can be created).
There are no ongoing orders (one can still complete orders with Energizers, however).
The total time needed to create the specified amount does not exceed 24 hours.
If the player decides to create an item with a missing component that is available in other factories, the component will be created first and will count as an order alongside the main item.
