("Though an idea for it would be a content switch." - What do you mean?): Could be a toggle in a menu for centaur content so that if someone has no intrest in it they can turn it off. but i don't think it's really necesarry.
Especially with the:( "Also you could always add an icon to any action that leads to a scene" - Do you mean in the dialogue? Like when the player chooses to start the scene I could add a heart symbol near the "yes" option. If I got this right ofc.) Because you got that right.
("I am curious if you at some point will release the option to get the full version for a single payment." - And again I don't quite get how it would work... Like buying the game here or on Steam? Or an option to buy only the build on the patreon/boosty w/o any subscriptions?): Yeah i mean like on here or Steam. though i know what is tricky with the whole payment processor debacles of late. could be that you buy a build or just decide on a price for what you value the game at which is always tricky. and you can adjust the price when you add more content.
(And I got the problem with the last moment. I'm planning to add the map + expand the storyline & add the option to ask Shaartan again about what happened so you could find the attack spot easier. And if you want to find the spot just check few comments below, I added a screenshot there.): Some sort of map would be nice. but i know developing and implementing thing can be hard and time consuming. Glad to hear you are planning it so i'll look forward to it in the future. And yeah i found the comments and screenshots that helped me figure it out :D.
