Dungeon of Lewdity is a CYOA type story in which you play as a lewd elf girl with nothing to lose who throws herself into the dungeon of lewdity in search of power, riches, and excitement. Depending on your choices, all kinds of crazy things happen, warping your character's body and mind as she passes through the dungeon.
The game consists of your character moving through individual rooms of the dungeon, and occasionally making choices as to how to confront the challenges in question. Confronting the challenges intelligently or lewdly can boost those stats. There's hentai pictures all over the place that are at least obliquely related to the story being told. Should you manage to complete the dungeon, your character will be rewarded, though the reward sought might have changed due to the dungeon.
In any case, the game does what it set out to do, but it's not particularly deep. There are technically two stats, but they are very rarely checked or boosted. In addition, after the first two or three choices in the game, you're basically set on a path, future choices just confront individual rooms/challenges. Your generally at the mercy of the dungeon; your choices have very little agency. Overall, I felt like the game was worth playing, but nothing to tell your friends about.
