I'll have to look into adding a bit more UI feedback for items! The bodies in the world don't despawn. If you wait long enough, you'll see than an NPC will actually collect it and destroy it in an incinerator. Or goblins will collect the body, take it to be sacrificed, and turned into more goblins. There are some LODs in place for trees, but some more props could probably use them! Yeah, currently there aren't combat levels but that will be added in the future! I had something similar to runescape's skill system in mind when building it out for sure. :)
Thank you again for playing! :D
