Shit, I wrote an in-depth review, but clicked outside the message window by mistake so it disappeared and I lost everything. So I'll make this one a bit shorter instead.

Update: Looks like I utterly failed at that

Anyways... Game is fucking great. Great writing and surprisingly good art for a text-game. Especially, great choice in not allowing race/body options. Those things always results in shitty lewd scenes with an incoherent mishmash of useless customization information. Having a single generic MC in mind makes everything a lot more fluent and coherent.
That being said, even great things can be improved, so here's a few suggestions. All (or almost all) similar games suffer from the same problems I'm addressing so it shouldn't be taken as a criticism for this particular one.
Suggestion 1: Kill All Battle Repetition
If I use the same butt-fuck attack 37 times in an encounter, I don't want to read through the same text each single time. You can't possibly make 37 unique descriptions so just give us the ones you got and then whenever I use butt-fuck attack again, simply write an effect summary like this:
----------------------------------
Butt-fuck Success
Monster +42 arousal
You +9 arousal
----------------------------------
Suggestion 2: Kill All Other Repetition Too
So I meet some red slime chick a second time and half-way through the text I start thinking "did I read the exact same thing an hour ago". Now half my brain is occupied with that question. A bit later I realize the question is "yes" and start clicking to skip, but what if something new comes along? Well, I can use the ren'py "only skip seen text" option (if it worked), so I don't click through unseen text by mistake, but then I don't remember the context.
More importantly, all this shit removes focus from the story and breaks immersion. If there's a situation where dialogue would be repeated, then write it away. If I meet red slime chick again and it will ultimately lead to battle, then just start the battle immediately. If it leads to a decision instead, then make the dialogue short so I remember what it's about but doesn't waste time. Oh, and make it obvious which choices I've already made.
Suggestion 3: Kill All Unnecessary Clicks
If I've surrendered to the red slime chick and things are getting hot and dirty in a lewd scene, I don't want to click every 3rd-10th second just to read the next few lines. Make 60 pct of the leftmost screen text, place the picture on the right of it (or vice versa) and remove all other visual distractions (buttons, stats etc).
Suggestion 1-3 aren't just "nice to have". They're absolutely critical for how a game feels. Imagine a 4 hour movie that constantly repeats the old scenes and stops every 3rd-10th second until you click. Sure, you can just fast-forward and click when needed, but you're not really enjoying the movie the same way anymore. The writing in this game is goddamn great and it is a shame I can't enjoy it fully because of these technicalities.
Bonus-suggestion: Lewd Content Accessibility
If you relentlessly murder all repetition like a rabies infected hamster on meth, then what if you want to experience a particularly hot scene again? One way is to simply make it available as a specific dialogue option or an even easier (but less immersive) option is to "dream" about them in the inn.
Regardless of the choice, I can't see a reason to keep content from the user. For instance, I beat the red slime chick on the first battle, but then read in the wiki that she had a loss scene that is now inaccessable to me. Naturally, I immediately began crying hysterically and then just felt empty. Incomplete. This seemed like the only rational response instead of, you know, re-loading an old save.
Not only do the player miss good material this way, but he's also forced to repeat the same battles. Some encounters even have several lose scenes depending on how you lost. Then you have to repeat them each time to somehow end in a specific position and if you fuck it up, you have to do it again and again. Better to just unlock all relevant content when you beat a specific monster girl. In red slime girl's case, I could ask her "what would have happened if I lost" to which she'd say "let's find out". Or I could, as mentioned, just dream about it.
I don't want to end on a negative note though, because this is a great game compared to the rest of the genre. Yes, I know I'm repeating myself, but hypocrisy is an important aspect of being a leader, and if writing shitty reviews of porn games for free is not the physical embodiment of true leadership then I don't know what the hell is.
