I don't know can I ask or not but I saw some of your buildings have some kind of objects like Bushido and wood blocks can Change directions, so may I ask what those mod are?
The second - https://community.playstarbound.com/resources/castlevania.2807/ Objects like Bushido?? About the first I can only guess! But nothing comes into my head.
I assume you mean that you want ideas for new items? I am not sure what your mod already has but I may be able to help still; have you ever looked into Japanese myths and folklore? Perhaps there is some inspiration to be found there.
