Pretty good game so far, though I dislike that all the lewd scenes are forced, and so far, only happen with extremely slutty girls. Not a fan of slutty girls, personally, so it may end up being a dealbreaker for me. Otherwise, story isn't bad, but dialogues are way too verbose. Renders look pretty good, and LIs are attractive. Incest tag is premature, as the sister still isn't even on the same continent as of the current content.
The lewd scenes are "skippable", but not really. Even if you "skip" the Rose scene, it doesn't jump far enough to avoid an unpleasant eyeful, which makes the "skip" option totally pointless. Dev doesn't have enough respect for his players to even offer proper skippable scenes, much less letting us choose who MC gets with.
Rose having a giant, prominent queen of hearts tattoo had me wary of her from the get-go. Wasn't sure if dev actually knew what it meant, or just thought it was gambling-related, but it seems like it's actually, and unfortunately, fitting for her. Definitely not harem material.
Edit: Forgot to mention, it's also currently a kinetic novel, and doesn't seem like that is going to change. Aside from the almost-skip scene choices, there was only one other choice, which slightly changes one very small interaction, but no variables are ever set or checked, so that one choice is meaningless, and doesn't affect the story in any way.
