Not to mention the other elephant in the room. Threshold isn't an artist, so they have to pay artist a lot of commission if every skill and scene have artwork.
And I don't even consider this as a negative. I would rather this game have no image but have more complex mechanic like Lilith's Throne (before that project went completely into the gutter). Been wanting a partner, if not a full party system from the start. A waifu adventure game just doesn't feel the same if you can't take your favorite waifu to adventure with you.
It's a crowdfunded 18+ RPG that has a ton of great customerization featuress, that has since went into the gutter due to the maker's inability to keep a proper update schedule, and the constant emotional validation/pampering from their discord crowd. You could still find the latest version by searching the name, play it and form your own opinion on the game (I'm personally in the 'love the game, not loving the creator's workflow or lackthereof' camp). Although I recommend against donating for the project yourself since throwing money at it (as its diehard fanbase already done) doesn't seem to help move the development along.
