Very promising start. Definitely more of a slow burn NTR, which isn't for everyone, but for people who don't need tits shoved in their face every ten seconds, this is great.
Pros:
-Futa NTR. Not enough games have this. Always need more of it.
-The MC doesn't fit into the obvious, and horribly overused, tropes that a vast majority of NTR games use. Instead of the vaguely nice, sweet, and criminally oblivious/stupid character that is a total pushover, he actually has a bit of backbone and is a powerful warlock that can handle himself in a fight.
-The NTR itself is well done so far. Early days still, and we haven't gotten to anything super spicy, but it's nice to see her use different strategies to corrupt each character. It feels really nice to see the characters corrupted in different ways rather than just watching the same basic premise played out five different times.
-You aren't forced to just bend over backwards for the maid. You don't have to bone her if you don't want to. Most players probably will, and we don't know if these choices matter (really hope they do, multiple endings are always great in these kinds of games) but having even a little bit of agency is good for the story.
-The princess is actually really sweet, and I really like the scenes where she's trying to show initiative and advance her relationship with the MC. I almost wish there was a path in the game where the MC says fuck it to the harem, I have a princess who loves me and will do anything for me. Very unlikely to happen, but still, I like her, and I almost feel bad that she's going to get corrupted by a futa demon. Almost.
Neutral
-The models for the characters are very, VERY obvious honey select models. They aren't bad, but they aren't spectacular either. Some people will probably complain about this but overall, it's whatever. Most of them look fine.
-The maid is very well done, but one thing I am left wondering is why she's obsessed with the MC. He hasn't shown a lot of affection towards her and isn't exactly charismatic. Hoping her attachment to him gets explained later on in the story.
Cons:
-The MC, while dodging several of the worse character tropes in an NTR game, is still a bit of a dork, and his dialogue falls a little flatter than most other characters. So far, he's mostly been characterized as a horny little bastard that's kept in check because he's insecure about his dick size. While amusing, we really haven't gotten too much else from him yet, and I'd like to see him get a bit of depth as the story develops.
TLDR: Great start to what could become an excellent game. Look forward to more!
