Leave your morals and decency at the door, this game holds no punches.
I've played a lot of adult games over my lifetime - I remember playing many early adult dating sims and 'adventure' games where the rewards were lewd pictures.
There is absolutely nothing to compare this game to, it stands on a pedestal on it's own.
This game is not only fun, challenging, open-ended, and sexy - but it's also completely player-narrative driven allowing you to essentially do whatever you want within the game's boundaries/engine.
There is almost too much to go over as far as events/story, but what I can detail is the mechanics of the game.:
X) Stats that you must level such as 'skulduggery' which will progressively allow you to picklock harder and harder locks allowing entry to places with better loot or different scenes depending on context.
X) Skill-based sexual acts where your character will get better at 'getting people off with their mouth' if that's the direction you want to go, there's a lot of skills/stats in this regard and it's a lot of fun leveling them up too
X) Options to change the gender of practically every meaningful character, not that it matters a ton to be honest because quite a few characters are simply described through text, but it's a good touch nonetheless.
X) A relationship panel that allows you to see how much a character loves you and whether you're the submissive or dominant one in the relationship.
X) A well-done overview of the world map in addition to keyboard shortcuts for traveling throughout the city.
X) Special events that remind me of something like Animal Crossing or Harvest Moon where you need to fulfill certain criteria by a given day in order for something to happen.
X) A character creator/customization mechanic that only gets better over time as Vrelnir continues to work with others to add more clothing/customization into the game.
X) An insane amount of lewdity
I mean the tags alone should give you the hint, but seriously - hetero/homo, bestiality, tentacle, etc. You will probably scratch your itch with this game.
All-in-all this is probably the most feature rich and fleshed out HTML game that I can think of and I've wasted countless hours on it. I applaud Vrelnir for putting so much time and effort into the game and I look forward to the future development of it.
TL;DR - Just download it.
