True, but this is a porn game, not an accounting simulator. Having tiers of success could be fun and add replay value.
I agree that replay value would be good. But I am not sure, if tiers of success would do that trick. The game could be expanded where this activity is one of many or repeated with different variations. The game is cute, but basically it is like a mini-game inside a simulation game, only that the lewd office game around it is missing.
Yeah, yeah, it does stand on its own among all those "games" that last a few minutes, nothing wrong about short funsies. But one can hope for games with actual game play and lewd content.
