About this game

Stonewall Penitentiary is an indie murder mystery adventure that is presented in the visual style of graphic novels. It pays tribute to Agatha Christie's classic And Then There Were None and horror thrillers like Scream and Saw. Discover why you and six others were kidnapped by an unknown captor as you search an eerie prison and solve mind-bending puzzles to determine "whodunit!"

Will you survive Stonewall Penitentiary and its many mysteries, or will it be your tomb?


Stonewall Penitentiary is a traditional 2D point-and-click first-person adventure game with a focus on exploration and narrative. It features beautiful graphic novel-style artwork and cinematic music. Explore an abandoned prison by navigating from room to room. Separate inventory, map, journal, and character screens are available at the push of a button.

Stonewall Penitentiary plays like an interactive novel. Throughout the game, you will make choices that can affect the outcome. The game features all standard adventure game mechanics, including locations to explore, items to collect and use, characters to meet and interact with, and puzzles to solve--all without any major pixel hunting!


You wake up. The last thing you remember is lying in bed at home. But you aren't home anymore. Looking around, you quickly establish four things: you're in a prison; your clothes are missing; your hands are tied; and you can't remember how you got here.

You are William Thane, a middle-aged man struggling with depression and alcoholism. You, along with six others, are trapped in an abandoned prison, held captive by a sociopath obsessed with justice. But there's a catch: one of you is the killer! Can you escape? Success lies in your hands!


In Stonewall Penitentiary, there are seven suspects...and any one of them could be the killer. Who is it? You'll have to use your detective skills to find out!


Becca Ronni
Becca is a no-nonsense lawyer who is guarded and mistrustful. She didn't wake up in the same place as the others. What is she hiding?


Gerard Auberon
Gerard is a hard-to-read loner, and he likes it that way. He doesn't say much, but he seems loyal. Or is that an act?


Grayson Wilford
Grayson is a take-charge businessman who isn't shy about barking orders. But is he authoritative or self-serving?


Jessie Bartlett
Jessie is a friendly, inquisitive teen girl who doesn't hesitate to let others know what she thinks of them. Does she have a dark side?


Louis Algar
Louis Algar is a D-level actor with a sick sense of humor and a huge ego. Could this all be a game to him?


Sonny Peyton
Sonny is a shy computer programmer who, despite being terrified, is quite resourceful. Why is he so helpful?


William Thane
Will is a down-on-his-luck painter who is currently unemployed and struggling with both alcoholism and depression. Throughout the game, you play as Will...but that doesn't mean he isn't also a suspect!

    Summit of the Wolf Trailers and Release Date

    Hi all! I am extremely excited to announce that Summit of the Wolf officially launches on April 21. If you haven't yet, add it to your wishlist today! In addition, trailers are now available on the store page. Since there are two sides to every story, and Summit of the Wolf takes place in both a fantasy world and the real one, I made two trailers--one to showcase each part of the story. As you'll see, they are drastically different in tone. This is intentional! Enjoy, and don't hesitate to contact me with any questions. Thank you for all your support over the years! All the best, Christopher

    Summit of the Wolf GUI Colors

    Hi all, My beta testers are split right down the middle, so I'm asking on all social media: which color scheme do you prefer for the GUI? Keep in mind that this is a fantasy game intermixed with dark real-world segments that features a young girl as the protagonist. https://steamcdn-a.akamaihd.net/steamcommunity/public/images/clans/33849275/ce09ccd6f082fe3d547c42487f30242c96358fdc.jpg https://steamcdn-a.akamaihd.net/steamcommunity/public/images/clans/33849275/421048be495107495fbc049dc86cef6df6c5790f.jpg Please comment with "pink" or "beige" to help me decide! Thank you! ːsteamhappyː

    Summit of the Wolf: Beta Officially Begins

    Great news, everyone! Summit of the Wolf is now officially in beta! Stay tuned for an official trailer, along with a specific release date, coming very soon. For now, however, I'd like to finally discuss the real-world segments of the game, which I've been promising to do for several months now. As I've alluded to in the past, Summit of the Wolf takes place both in a fantasy setting and in the real world. While the majority of segments take place in the former environment, the latter is integral to the story. Whereas the fantasy segments could be defined as a "fairytale," the real world segments are most definitely a mystery. What happened to Ophelia, the game's protagonist? How did she end up where she is? Concurrent to this mystery is the next chapter in the overarching metastory that has been set up since the first game in this series, Lifestream. In this chapter of that story, we reunite with two familiar faces: Kate Ekan from Shady Brook and Brianna Auberon from The Filmmaker. Kate is now a patient in the hospital in which Brianna works...but why is she there? And how do these two tie together? Not all the answers to the questions you'll be asking are included in Summit of the Wolf...but there will definitely be more than enough foreshadowing to keep you guessing until the next game in the series! https://steamcdn-a.akamaihd.net/steamcommunity/public/images/clans/33849275/c936a080494e37e56d99e713b26842b5b6039250.jpg Summit of the Wolf launches in April. Add it to your Steam wishlist today!

    Hey everyone, This is just a quick update to let you all know that I'm finally feeling well again, and I am back to working on Summit of the Wolf. I am currently 86% done editing the voices for the game. I estimate another week or so of editing. After that, I'll just need an additional week of testing before the game goes into beta! Summit of the Wolf is still on-track for a Spring release. I'll post a more detailed update at the start of February! Cheers, Christopher
