Items that you don't need right now can be put into your safety deposit box instead.
There is a soft limit on the number of items in the inventory, usually at 50, though upgrades can be obtained to increase the maximum capacity of the inventory, such as the Bigger is Better upgrade which increases the capacity of the inventory by 5 per upgrade. When the soft limit is reached, you cannot buy anything but you can still earn items from places like the Healing Springs.
Items kept in the Inventory can be stolen by creatures like the Pant Devil.
