0.30 seems to be a very big update an overhaul given the new 200 character sprites, would any of the establish quests changed and will it affect the saves of the game as well?
Nah basically all the existing content is exactly the same, its 200 NEW sprites, not remakes of old sprites. Saves should work just fine.
I see, thank you for confirming and I hope all is best, personal wise and with progress of the game wise.
