This is a great game, I can't recommend it enough. Does it have flaws? Yes, it does. There are fairly frequent grammatical errors and it's overly punishing when you pick the "wrong" dialogue options. With a game this good those are fairly minor concerns though, just make sure to use a walkthrough. The game looks good, has great characters and is fucking hot. I like the limited number of LIs that the game offers, as it allows the dev to focus on quality over quantity. I also love how this game offers multiple paths for those characters, allowing you to see very different sides of them and explore different kinds of relationships with them. I think that last part might be the game's biggest selling point for me. A game where you can either share a beautiful and tender romance with your sister or turn her into a loving sub is a win in my book.
