I need to address the possible components of the title: "Up to and Including Her Limits" as the core title, the sequel or expansion "4 Deeper," the year 2024 implying a release date, and "free" suggesting a free version. Since I can't confirm the exact details of a 2024 free release, the approach would be to either focus on the existing game and discuss hypothetical expansions or treat the entire title as a fictional piece.
