Update 02.023: Inventory system was added in this update. Players now have the ability to store items from the containers inside the player's inventory and see the full content of the storage containers. Additionally, we have added more construction models for blocks used in survival building, including the first batch of roof tiles. Also, players can't build on top of unfinished models anymore. Stay tuned for more survival features in future updates!
