Hi Oates! Nice game, really well polished. I'm having an issue with the Mac version though. Saving doesn't work on the mac version. I think this is a known issue with RPG Maker MV.
See: https://forums.rpgmakerweb.com/index.php?threads/mv-mac-deployed-game-save-issue-not-saving.75472/
There is a plugin mentioned in that thread as a temporary fix while Archeia tries to fix the issue. Hope this helps!
