Yes. Inventory currently has a maximum size.
I will make a way to recycle items that you don't want, then you can earn the マリモ from those unwanted items.

MOD is the amount of modifications the item has.
武器製作 and 防具製作 will be able to modify items incrementally.
You can use マリモ, 木材, and 鉄 to modify items. [Coming soon]
