The Industrial Academy is designed to upgrade factories, airplanes, and truck factories. Building becomes available from level 22.

To build the Academy, go to any object that can be upgraded and click on the upgrade icon in the form of a star ⭐. After building, open the Industrial Academy, and you will see a list of objects available for upgrading.

Characteristics that can be upgraded using ingots:

• 📦 The number of shelves for finished goods.
• ⏳ Production time and travel time.
• ⭐ The number of experience points for completing orders.
• 💰 The amount of gold coins for completing orders.

Note: Characteristics need to be upgraded sequentially to unlock access to all features. It is not possible to focus only on one characteristic, as the game assumes balanced development.
