Hi latone88,
The steam version includes shares from KADOKAWA/DEGICA/STEAM and has a different license from our direct store (Steam version is RPG Maker only, Itch.Io version is engine-free). The "updates" are for the people that bought directly from our store, it's not just faces but a new set of tiles that fit the fantasy pack we had too. RPG Maker Web have the same deal that if you buy directly from the RM store some resource packs have exclusive assets as a thanks for the direct support.
Because of said circumstances, I'm afraid I can't give you a copy of the itch.io version. I hope our explanation makes sense.
