Because sadly many people think full of euphoria it is easy to create another sex game, then do chapter 1 and either because of not enough interesst or because they burned already all of their euphoria they can not do a second update.
Not only this, when the base description of a product is different from it's content, people avoid to support financially, since they don't know what kind of product it will be.
Description said "CHOOSE EVIL OR GOOD PATH" and on the game you can only be good. People complained (myself included), dev gave zero shits to clarify about it. So, starting a game on impulse AND seeling something you're not delivering = fail.
well done game!
