Hi art926!
I have responded to your questions about the game's morality and sexuality in the following thread:
https://itch.io/t/709580/community-questions-thread
Currently, it is planned to entirely replace all of the default (or "RTP") art in the game, including tilesets, doodads/objects, spells etc, however this will most likely be in a future update.
Additionally, We are looking at making the game compatible with the itch.io launcher, but currently there is no ETA
Thank you for your question, and thank you for supporting us!
