About
Snow seals you inside a luxurious men’s spa. A guest is found dead. Your memory is fractured. Among the group of alluring men, one may be the killer. Suspicion grows, desire blurs with danger, and a tarot reading whispers of fate: The Devil. Death. The Lovers.
As Lucas, you’ll collect evidence, solve puzzles, and unravel the mysteries of Marble House. With six romance options, every bond you form could lead to passion - or peril.
Erotic thriller mystery - a snowbound luxury spa becomes a stage for murder, secrets, and desire.
Choices that matter - Lucas’s Charm, Guile, and Sense shape dialogue and relationships.
Investigative gameplay - explore environments, collect clues, and expose the killer.
Glass puzzles - reassemble fractured memory shards as Lucas uncovers the truth.
Six romanceable characters - pursue relationships and unlock explicit scenes.
Partially voiced - characters react with voiced emotes for added immersion.
Multiple endings - find love, solve the mystery, or fail entirely.
Gallery - unlock CGs and Tarot cards as the story unfolds.
As a solo developer, this game has been a labor of love for several years.
I am excited for players to enjoy the game for its narrative, atmosphere, and relationships.

3½ hours, done. It's very short. Nice graphics and nice mystery. Enjoyed all 3½ hours. I suppose I can go back and get the romance with them all and make it a bit longer.
It's such a letdown from marblehouse It has a lot of potential, and I love old 3d model and animations more. There are probably Demo out there on the internet. I encourage you to try that demo, and you'll know this is such a letdown. Because the AI graphic is so wonky, inconsistent, and funny, a lot of the time, from a person who has been following the development quietly for years
[spoiler]My fav is the victim >:([/spoiler] I recommend this as a Murder Mystery lover, the finding clues part is fun and the guys are hot BUT..... The game is short, only 4 chapters, so the romance and deduction happens very quick. No spicy scenes replay is bad, considered that there are only 1-2 sex scenes per character. This game has so many potential to develop. But for now I'm giving it a 3/5, considering the price also.
good plot, nice cgs, the game seems a bit short but it is worth with the price, need more sexual tension scenes in each routes, anyway it is good, in my pov.
It's an interesting Visual Novel! I recently got into the genre. I can say I enjoyed it a lot! Wish there was a way to repeat the intimate scenes and have even more endings. I have 2 endings so far with the character I shipped but I'd like more lol. I still recommend to anyone interested but hope there is some DLC or additional repeatable gallery content.
Amazing game! Absolutely loving it! Really enjoyed the storyline and all the CGs and animations. Already looking forward to next one!
its's a niche game, id say it did justice for the genre. overall -id recommend it if you are into the genre. pros: - the characters and vibes are nice; - fair amount of character variety; - price is fair, got mine on sale though price slights on the high side; - music nice; - story is fine overall; - no serious bug in my play-through. Improvements: - story could be with more layers, though it is consistent and smooth; - ai-scenes are fine, a couple more key scenes would make it great, especially adding more details; - gallery could include already unlocked romance scenes instead of needing to load from saves. - the in-game tutorial is a nice touch, maybe add a guide or story map during major turning points (it's ok without them for this game since story is linear) - maybe have a new+ mode for a true happy end
Marble Mirage was the first novel game to sell itself to me because of its unique premise. There are no other games with the same visual style, sound or setting. The colors, the music, and the plot are really great, and I won't say I didn't enjoy it. These are the reasons I would recommend playing it to discover all possible endings/romances and to open each artwork in the gallery. Sadly, this is the only paragraph about good things This game really lacks the depth it could have had, given its premise. As a writer, I truly see a huge potential and more possible actions/plot twists/dialogue options this game could have had. But in reality, we get a very fast playthrough that becomes shorter for no reason with each chapter It is also worth mentioning that having the main protagonist fall asleep is an insanely weak way to introduce the story. Sorry, but passing out every time we need to fast-forward the day and get to another one, especially with this strong thriller concept in a men's spa, is a big no for me. I understand that it ties into the plot, and only at the very end do we learn that some of the other characters felt the same way, but come on! Ain't no way you have so many opportunities with the idea you got in your hands, and you just let us faint every time here and there. This deserved a better production and writing AI is a flop in general, and I don't appreciate its use in art, but I knew it had elements of it in the game. Remember, the whole idea sold it to me, so I decided to get over the fact that it uses AI. But next time, please consider having art designers. Marble Mirage is not bad, but it deserves so much better
Loved the story, works perfect on Steam Deck. The game looks gorgeous. Highly recommend to those that are not AI adverse.
I really love the detective part of this game, but that's it. That detective part is too short, and the loveline romance is even shorter. I feels no chemistry for the characters that i'm about to romance, and there too few event to understand their character. All of the above is fine if the game didn't cost so expensive (for a game use A.I to draw the character no less).
