Inventory Expansions.

With treasures and pets added it would be helpful to have more inventory space to carry more items from mining instead of having to go mine for a few minutes to be full of space going back home and storing all of it in a chest after that short mining, would be better to explore for a while before going back to a world to store your items you got from a full inventory

PixBits should take a look at Fallout. When more items are in your inventory, the slower you move.

Fallout is designed to be realistic. This is not.

Maybe a backpack of some sort?
