Let me tell you, the seeds of a good idea are here. This game really does want to be good, and provide a good H-Game experience. The problem lies in it's unfolding complexity and poor choice of engine.
Labyrinth of the Forgotten Goddess has you exploring the titular labyrinth in a take on classic 90s dungeon crawlers that includes a decidedly kinky bent. You have the option to physically or sexually defeat your enemies, and the game favors the latter. The equipment and magic system is pretty robust, the combat is amazingly complicated, and the growing array of monsters are interesting and in line with many of my fetishes.
So why three stars?
Because Labyrinth is very much a 90s dungeon crawl. The interface is intuitive to people not familiar with the system, the game is really poorly optimized, causing bugs and glitches galore (which the dev is dutifully squashing but again, you choose Java as your engine), and the text is doing the heavy lifting here. Now, normally I'm fine with that, but the text here is not at all descriptive as to what's happening to you, requiring a heavy investment of imagination.
Likely a large part of the reason for this is there's a pretty wide array of fetishes on play here, including the ever cherished Bodypart and item TF. It's wonderful to see the variety, but the feature creep does mean not a lot of it is very well explored.
For what you're getting, there would have been better ways to go about it. The developer gets credit, though, for sheer breadth, and many fetishes you've sorely missed from other games can likely be found here, once you learn to navigate the system.
