Hi there! I'm so glad to hear you liked my stuff! I replied to your same comments via Patreon (hi again) but I'll post them here again for anyone curious!
(BELOW IS A SPOILER FOR THE GAME, BE WARNED!)
Satine is actually genderfluid/genderqueer and in the Epilogue Game, goes on a very overdue journey of gender discovery. It's gonna be a lot of fun to write! :D
(SPOILERS END HERE)
From what it sounds like, you probably have a version of MAC that won't play Ren'py games Apple requires *ALL DEVS* to put about $100+ towards getting their game "authenticated" to be played on their devices. <:( It's something I'd like to eventually do for the Epilogue game, but right now I just can't afford it, especially when the game is coming out in chunks and isn't completed yet.
If you had an android phone, I am going to release a mobile version soon that should hopefully work!
Otherwise, there's not much I can do! I'm so sorry! ToT
Older versions of MAC can still run Ren'py games, but I know after a certain update they stopped functioning.
