You missed his entire point regarding the mutation system, bro.
The problem is that the predicament he happened to state above is not only contradictory but completely subjective in nature.
He claims that CoC has a lackadaisical customization (mostly from clothing articles, which mind you for the type of game CoC is, is a tertiary matter and not the primary focus of the game, as the game sells itself on its mutations.), as well as an rng based mutation. And a few sentences in he clearly contradicts himself by stating that CDDA also has its own implementation on random mutations. Unless his gripe is the fact you cannot choose which part of the body you mutate, then that is something that is counteractable in LT, given that the slime route gives you this option. The clothing point also does not take into account that cdda is a rpg game, where equipment plays a vital role in protection against zombie bites and etc., for example project zomboid (I strongly recommend this game). From the cursory glance i took of the game, it is a zombie apocalypse themed game, in which case clothing layers is more probably than not influential in how easy it is for you to be infected. Another point is that cdda is not an adult game, its adult theme from what he stated comes from a mod, in which case cdda isn't even the best or a contender when it comes to character customization, as now we can consider the likes of CK3, rimworld, and various other top shelf games with adult implementations through mods.
Now for the part where all of what he stated as negatives is completely subjective in nature. Some people prefer the randomness of mutations, while others prefer a more static system for mutations, and i for one prefer a mix between both worlds, as i appreciate the work that would have to be put to make that possible (which LT does). How hard it is to acquire something may break a game for some, and make a game for others (for example ck3's atrocious rng), which is why i believe what he stated on the randomness of mutations as a subjective matter. Another point is that LT is a text-based game, so if they were to implement your system of extensive layoring, it would prove a cumbersome task to add that to the game besides being used as flavor text, which would be ridiculous, as the removing of those articles of clothing during the more lewd scenes would be preposterous and even humourical. CDDA though does not suffer from this point, as i doubt there are many mentions of the process of removing your clothing in the base game itself.
He seems to be in the wrong place, as what he wants is not a text-based adventure adult game, but an rpg or life simulation game not focused on the adult theme.
[edit: Also given LT's mod support, and open source nature, if someone were actually that perturbed by the matter of a lack of clothing layors, they could mod that feature in just like how the adult theme in cdda was modded in.]
