We are working on bringing new systems and being able to test all the possible improvements in Early Access, among them is the Inventory system, for this we kept in mind 3 things.
1st) We are bored of being limited in inventory, so in Early Access you can save without limit.
2nd) Be accessible in real-time while playing, even be able to use hotkeys. This is due because the Monster Girls and normal monsters could attack you.
3rd) Be able to distribute your belongings in different chests, in this way when you build your Kingdom you can create a room and organize everything in it. In the future we are considering making a weight system, so the more you train, the more weight you can carry (items).
