Overview
Freyline is a fantasy roguelike deckbuilder for players who want corruption-driven card combat with a self-aware sense of humor. It leans into over-the-top campy tone rather than serious drama.
Story
Freyline is a Holy Paladin set on breaking a corruption curse, though the game itself winks at how these stories usually end for characters like her. The premise plays out as a battle between her resolve and the curse working against her with every encounter.
Gameplay
Runs are built around turn-based card combat, where players assemble and adjust a deck to fight through enemies while managing a possession mechanic that can turn against them if left unchecked. Between fights, an enemy gallery lets players experiment with deckbuilding options tied to the monsters they've faced. Corruption acts as both a threat and a system, pushing runs toward failure states that double as content in their own right.
Features
- Turn-based deckbuilder combat layered with a corruption and possession system
- Monster girl and gender-bender transformation themes woven into enemy design
- Strategy-focused card choices that carry over into an unlockable enemy gallery
Notes
Artwork is AI-generated CG rather than hand-drawn, which shapes the visual style throughout.
Installation
Installer option:
1. Install game and run
(SHA hash available below if you want to double check my pc to your pc is the same thing)
ZIP option:
1. Right-click the .zip → Properties → tick Unblock → Apply
2. Then extract the whole folder anywhere
3. Run ADeckOfHex.exe.
(No installer, nothing written to the registry)
Note: The build is unsigned (not going to pay hundreds of dollars to sign it) so unblocking first per step 1, is what stops Windows showing "Windows protected your PC". If you skip step 1, you'll get that prompt and need More info → Run anyway. If you are uncomfortable with that, the game is also on steam and itch.
If the window opens blank: install the Microsoft Edge WebView2 Runtime (ships with Win11 and Win10 since mid-2021) from https://developer.microsoft.com/microsoft-edge/webview2/ . The game is build to run as a web app, this plugin enables that.
