Creator of the amazing Leane and even more impressive Leane 2, this time the dev created a dungeon crawler. It has a ton of HCG, and fun H game mechanics such as captured, enslaved, NTR statistics, impregnation+pregnancy progression, and an added in-combat rape with specific enemies against specific female companions. However... There are some glaring flaws in the game philosophy that makes it a worse H game than it should be.
The H game is exceedingly slow to get going, the introduction and then reaching the point where you have finally all the female companions plus the main female cast (currently only 1 girl) and a reliable way to trigger their NTR events takes hours of setup and only gets easier after you've taken the currently forced NTR event chain with the main girl in the story. Story is normally important for NTR, but in this title it's mostly an afterthought, a quick mindbreak or some dick and the girl is easily swayed. The incombat sex requires you to grind a fair bit before you can encounter the enemies, the NTR events less so, but you do need to spend a lot of time back and fourth clicking at the inn service or having them get captured and then finding specific moments in map dungeons/areas to see the H scenes for said capture, unlike in Leane where it was just checking on the orb button.
Overall, the biggest flaw is simply from the ground up it was designed in a way that would make the acquisition and enjoyment of the H content tedious and boner killing, despite having so many H mechanics and so many HCG to complement the downtime. Perhaps this is an issue with dungeon crawlers in general, or simply a case of too much game. In any case, this is a hard sell that I recommend playing the first 10 minutes and seeing if it's for you. I wouldn't blame you if you dropped this for a gallery save, it's just too much of a commitment with isolated pockets of progression in-between dick holding. Shame too, this dev's H games are generally fantastic H mechanically speaking.
