the problem being, without multiple save slots, you can't really save before the fun bits, and go back over them when it's time to get off, like most renpy games, or other titles coming with a gallery where you can unlock scenes after going through them once.
most people probably aren't going to be able to wank to this sort of thing if they've got to wait like 5-10 minutes between scenes, after all, and while a patreon donation would make that trivial thanks to access to a gallery, no multiple save slots makes that almost impossible, when it definitely should be a feature. that's why with renpy they've got like a hundred+ save slots.
like you said, the game is designed around a cyclical story structure, so 'keep going' rather than turn back to an older save is the 'right' way to play it anyway, so multiple saves isn't so much a gameplay bonus, that should be denied to the 'casual' player of your game. it just stops the game from being good flogging fodder in general. excluding save slots does nothing for the kind of game this is, but eliminate it for it's presumably intended purpose.
cheats and full gallery unlock and your work in general is worth the one dollar, sure. multiple saves, i think you should change, however. it's not about making sure you can go back and make different choices, as, again, your game looping around makes that entirely unnecessary, but no sort of 'unlock scenes in the gallery' versus full unlock, and no save slots to be able to get to the good points and come back later, means it's not really a good game for the sort of activities the games this site has on it...
it just kinda feels like a paid game that you've worked around so its not too obvious, but in practice still works out that way. we've got access, but unless we're screencapping the good bits, it's not really that useful as an erotic game. maybe as a novel experience, but not really someone intending to get deep into the game will probably want to stick with, outside of the story.
