Hi.
Thanks for your feedback. You can find mediafire link here.
Compression format will change in the next version, I get through this with trial and error just like any other dev.
"weirdo sexual fetishes" are not existant at the moment, at least in the main game. There are some in Whispers system, but you'll never encounter them in a normal game, unless you become a high-tier subs to see some. They will appear in the future, but will be avoidable, without a doubt.
I do make my game as a whole piece, so the choices that you make will always matter. There aren't a lot of them, and it's pretty much linear game with sandbox elements, but once you've given a choice, it will matter.
I am afraid not, you won't be able to romance just one character, you'll get close to everyone eventually, which is a point of making a harem game.
Let me know if you have any more question.
