I tried to like it, but yeah it is WAY too grindy to unlock the CGs, the story is bland, your character isn't questioning anything, he's just there like "Oh, a succubus, cool" and goes along with it. (but we don't play those kind of games for the story anyway so that's fine, but it's still not great), and the art style animation is... the same level as those old porn game that you could've found on the net using adobe flash. The main sex scene of the game is way too jiggly/bouncy, but the other CGs barely has any movements and the proportions of the girl is off (and the dick size and shape of the MC changes in every CGs lmao)
