Hm, your critique is more about the game's style, rather than its quality. Some AVNs are more linear and some are more sandboxy. The linear ones usually have fine tuned pacing and more immersion while the sandbox ones offer more freedom. I prefer the linear ones!

The in-game choices do matter, but there indeed aren't major story branchings, save for the endings.

Humor is subjective, but for me and for most it's one of the game's big strengths.

Including the option for biological incest in AVNs is problematic, sadly. The big credit card companies are projecting their own values on the content they help monetize. That's why platforms like Patreon, Steam, and even Itch, saw themselves forced to "disincentivize" flavors like incest. To circumvent this, you can usually find fan-made "incest patches" for AVNs on the internet. Or some AVNs use landlady/roommate as placeholders and offer the player to customize these role designations, as long as the players type it in themselves.

For this game however, I find the step-relationships very fitting. You don't need an incest patch for this one.
