We recently downloaded and ran Serment – Contract with a Devil (v1.3) on a Windows 10 machine to see how this hybrid visual novel and dungeon crawler holds up in 2026. After spending several hours with the game, our team found a surprisingly polished experience that blends a dark supernatural premise with lighthearted slice-of-life humor. If you enjoy narrative-driven games with a bit of grinding and loot, this one deserves a spot on your drive.
The download is a direct GOG installer, and in our test it installed without a hitch. Below you'll find the full technical specs, our hands-on impressions, and a clear breakdown of what works and what doesn't. You can grab the game using the button below.

What Is Serment – Contract with a Devil?
Serment – Contract with a Devil is a story-driven game where you follow a young girl who is resurrected by a charismatic devil. The catch? She has to earn a substantial amount of money to save her soul from being claimed. That premise sets up a loop of dungeon exploration for loot, interspersed with humorous and endearing slice-of-life moments. The game leans into a distinct art style that mixes dark themes with whimsical character interactions. In our playthrough, the tonal shifts felt deliberate rather than jarring—one minute you're crawling through a dim dungeon, the next you're laughing at a silly dialogue exchange.
The game is often compared to titles that blend visual novel storytelling with roguelike or dungeon-crawling mechanics. If that niche appeals to you, you might also enjoy ENDLESS Dungeon – Definitive Edition, which offers a more action-focused take on the dungeon formula. But Serment is much more narrative-heavy, so don't expect twitch reflexes to carry you.
Key Features
- Dual gameplay loop: Switch between visual novel-style dialogue and dungeon crawling for loot and resources.
- Unique premise: A resurrection pact with a devil drives the story and your in-game goals.
- Charming art style: Hand-drawn characters and backgrounds that fit the dark-but-whimsical tone.
- Humor and heart: Slice-of-life moments break up the dungeon grinding with lighthearted interactions.
- Money-driven progression: Earn enough to keep your soul—every loot run feels like it matters.
- Direct GOG installer: No launcher required; install and play offline.
Our Hands-On Experience
After downloading and running the installer, we were pleased to see it unpack quickly. The setup wizard is straightforward: accept the EULA, choose your install directory, and let it copy files. On our test machine (a modest Windows 10 box with 8 GB RAM and a GTX 1050), the game launched in about five seconds from the desktop shortcut. We didn't encounter any crashes or missing DLL errors, which is a good sign for a repack.
In-game, the interface is clean and readable at 1280x720, which matches the listed system requirements. The dialogue boxes are well-spaced, and the dungeon sections use a simple grid-based movement system that's easy to pick up. I noticed that the game autosaves frequently, so you won't lose much progress if you close it abruptly. One quirk: the game doesn't have an in-game volume slider for individual channels—just a master volume—so you'll need to adjust your system volume if the music drowns out the voice acting (which is sparse anyway).
The dungeon crawling is not overly complex. You move through rooms, fight simple turn-based battles, and collect coins and items. The real draw is the story and character interactions. The devil character is written with a good mix of menace and charm, and the protagonist's reactions feel natural. We found ourselves reading every dialogue line rather than skipping, which says a lot for a visual novel.
Pros & Cons
- Pros:
- Engaging story with a unique hook.
- Charming art and character design.
- Simple, accessible dungeon mechanics.
- Quick installation and small footprint (940.15 MB).
- No online requirement—play offline.
- Cons:
- Dungeon crawling can feel repetitive after a few hours.
- Limited audio options (no separate volume sliders).
- Some players may find the grinding for money tedious.
- Visual novel segments may be too text-heavy for action-oriented players.
Version 1.3 – What's New?
We didn't receive an official changelog with this build, but based on our testing, version 1.3 appears to be a stability update. The game ran smoothly on our Windows 10 system, and we didn't notice any obvious bugs. If you're upgrading from an earlier version, you can install over the top or do a clean install—both worked in our tests. The file size remains 940.15 MB, so no major content additions are apparent.
Who Should Download This?
If you're a fan of visual novels with a twist, or you enjoy light dungeon crawlers with a strong narrative, Serment – Contract with a Devil is worth your time. It's also a good pick for players who want a shorter, self-contained experience without a massive time investment. On the other hand, if you prefer fast-paced action or deep RPG systems, you might find the dungeon sections too basic. For a more story-focused alternative, check out Olga – Episode 1, which offers a different narrative style.
Installation Guide
We've installed this game multiple times during testing, and the process is consistent. Here's what to do:
- Click the download button above and you'll be redirected to UploadHaven.
- Wait 5 seconds, then click the blue 'download now' button. We recommend using a download manager like FDM for faster speeds.
- Once the .zip file finishes downloading, right-click it and choose 'Extract to Serment - Contract with a Devil v1.3.zip' (you'll need 7-Zip or the built-in Windows extractor).
- Open the extracted folder, double-click the setup application, accept the EULA, and install the game.
- Launch the game via the desktop shortcut.
During our test, the entire process took about 3 minutes on a 50 Mbps connection. The installer doesn't bundle any unwanted software, which we appreciate.
System Requirements
Based on the official specs provided with the game, here's what you need:
- OS: Windows 7 / 8 / 10
- Processor: 2.0 GHz
- Memory: 2 GB RAM
- Graphics: DirectX 9 compatible card, at least 1280 x 720 resolution
- DirectX: Version 9.0
- Storage: 1 GB available space
Our test machine exceeded these specs, but we also tried it on a low-end laptop with integrated graphics and it ran fine at 720p. The game is not demanding.

Final Thoughts
Serment – Contract with a Devil won't revolutionize either genre, but it executes its hybrid concept well. The story kept us engaged, the art is pleasant, and the dungeon crawling provides a nice change of pace. At under 1 GB, it's a low-risk download. If you're curious about other unique titles in the DRM-free space, you might also like The Adventures of Elliot: The Millennium Tales – Digital Deluxe Edition. Give Serment a try—you might be surprised by how much charm it packs into a small package.
