First off, it’s very important to know that this is a heavy NTR-oriented game, not a wincest game. Don’t make the same mistake I did going in. If you don’t like NTR, please steer clear. But if you do like NTR, which I will never understand how your brain works, you’ll probably love this. There’s a wide cast of characters, from the fatty uncle to the asshole hero and more. The art is absolutely gorgeous. I genuinely hope I can support the artist again in a future game that isn’t NTR. Also, bonus points for Black Souls easter egg. (the platform puzzles for black souls secret dungeon is ass btw please never do that again.)

TLDR: A complex and well done game with great art, writing, translation and design. But with a dark side that will leave you disturbed. PROS: This is a surprisingly good game. I like the fights and the RPG elements. The art is pretty. The writing is quite good. You care about the characters. The translation is near perfect. CONS: It takes a long time to figure out how the inventory works. The weapons. The upgrades. The items. The memories. They are all tricky to make work the first time. And you get few hints. So, that part could be better. As hinted strongly by game’s title, there is a lot of NTR/Horror. And since you care about characters, It will hurt when they get lied to and taken advantage of at every turn. The main characters are not very bright. Eventually, if you allow it, the heroine will stop fighting and become ugly herself.

This is a super high quality RPGMAKER game. I would consider it up there with Karryn's Prison. Before you think about buying this if NTR is not your thing you wont get anything out of this game besides a few endings. That being said this game offers a deep story with branching paths depending on how you navigate the game. Will you keep Trina pure the whole game or will you let her fall to corruption as her demoness nature takes over. That being said the combat is pretty solid. You actually have to manage your resources in this game such as mana and, energy. It also rewards smart play with its stagger system. The CG's in this game are top of the line and the scenes are plentiful and diverse. I particularly enjoy her demon scenes. There is light animation when it comes to pixel art but no live 2d I would say this holds this game back a little. One other thing I disliked about this game, there seems to be some areas that feel incomplete or rushed. Im sure there will be DLC to fix this issue though so I wouldn't worry about it there are after all 100+ scenes to collect. I think this is worth the price for what you get I give it a 8/10

A lot of mechanics and things to do/places to go. Also a MILLION times better then the stuff you see here on steam lately. Adult games are basically shovel ware and/or AI slop for a quick buck. An ero game that actually has content and effort put into it is so rare these days that you should really give it a try.

I really loved how much attention the game gives to small details. The weather, the crafting, the different ways you can progress are all surprisingly well done for a game like this. I ended up being very satisfied.
