Just to be clear, in my case I'm sharing comments from the dev regarding harem and poly more as a public service announcement, since many people seemed to have no idea this game isn't harem or that the dev has a bias against poly in general.
I have paid for and supported this game. But until I dug into the Discord and searched around, there was little indication that this seemingly is going to be a monogamous-ending-only game.
That's fine if that's their creative vision and preference. But it honestly feels almost like a bait and switch compared to the game flow so far, and it left a poor taste in my mouth upon learning their plans.
