Oath of Fallen is a 2D RPG Maker adventure sandbox by Drunken Skald. You play Vesperine, adopted daughter of a hunter in a remote village, drawn into events that reshape a world under the Cult of Light. Mysterious forces awaken demons and corruption across a once peaceful land, exposing a harsh society that judges anything outside its definition of good. The game uses 2D CG artwork and emphasizes a female protagonist facing rigid dogma and merciless judgment.
The current build is v0.04a, released September 8, 2026, and development appears ongoing. It runs on Windows in English and is uncensored. The update fixes graphical issues with the Dune Crawler, event problems, Teleportation Gemstone acquisition with save compatibility, and an options menu error during battle. It also adds a prologue skip, missing Cult Robes graphics for Ves, and a way to return from Zarim to finish an ingredient gathering quest. Earlier 0.04 added eight side quests, a stealth quest with detection, four repeatable quests, and many new locations.

New/Improved Mechanics
Completely overhauled the Pleasure, Lewdness, and Corruption systems
As previously announced, there is now a fully functional system controlling
Pleasure and Lewdness progression.
Some progression restrictions are still present, but they are now tied to
character development rather than being arbitrary limitations.
Raising Lewdness beyond certain thresholds will require sufficient
development of specific erogenous zones.
H-Events can now have different variants depending on Ves's current
Lewdness and Corruption levels
Defeat Events currently have three different variants.
The highest tier will most likely not be accessible yet, as Ves cannot
currently raise her Lewdness high enough to reach it.
H-Combat
H-Combat is finally here!
This is a system I've been quietly working on since the early stages
of development, and after overcoming several technical issues, it is finally
active in version 0.04.
Whenever Ves is Restrained, H-Combat visuals are now displayed, with actions
from the H category visually represented during combat.
Enemies receive an additional Endurance bar, which decreases as H-actions
are performed.
If the player does not actively contribute to defeating an enemy through
H-Combat, they will not receive EXP from that enemy.
The number of skills and actions allowing Ves to actively participate in
H-Combat and defeat enemies faster will continue to expand in future updates.
UI & Technical Improvements
Various minor UI improvements
Improved resource usage and general game optimization
The new Defeat Event system significantly reduced the overall size
of the game, despite the increased number of graphical assets.

Fixed (hopefully ) all missing graphic issues. The game no longer contains the temporary duplicate file copies used during the migration process.
Fixed several events, including the cultists near the dungeon and the guard.
Fixed the Dune Crawler and Sand Worm encounters. They should now select and execute their intended actions correctly.
Fixed the inn sleeping event. It should no longer walk around.
Fixed the clothing repair system. The related error should no longer occur. The UX has also been improved: after using a Sewing Kit, the repair window now remains open and displays the current condition of your clothing and the remaining amount of thread, allowing you to continue repairs until you're satisfied with the result.
Fixed several typos.
Major fix patch:
Fixed various book-related issues.
Fixed several transfer and teleport events.
Fixed the Pink Slime AI issue.
Fixed the Cultist Cave progression for players who refused the cultists' offer.
Fixed Phantom Arrow.

Many efforts, but so far rather poor execution, even for the Proof of Concept. 1) The game is lagging with poor FPS when you walk, while nothing fancy is happening on the screen. This would snowball into a laggy mess…
