Well, finally got around to playing this one. I have to say that I liked it a lot more than the previous game, the one with the goblin. It has its issues, but the gameplay loop is a lot simpler and it's a lot easier to get in a comfortable spot where you can do whatever you want whenever you want just to see lewds. You don't have to worry about stupid capture crystals and whatnot either. The fact that you can build a facility that basically captures adventurers for you is great, and the other game could have used something like it tbh. Building up to the ability to capture adventurers in any great numbers was way too tedious in that game...
Also, not a lot of games that really play up the transformation niche tbh, so I'd have probably liked it even if it had more issues than it already does... like the fact that you don't have a real gallery of any kind... either that or it's bugged.
In any case, the biggest complaint I have is that the succubus herself doesn't appear in any action, even though presumably she's fucking all of the adventurers she captures. It's not clear if she can just go futa whenever she feels like it or just uses her tail or what...
