About

Delivering letters in Dawnreach is just the cover story. The real work happens in the downtime, where a novice courier can spend his hours preparing for a disaster that's already on its way, and how much groundwork he lays now decides how bad it gets later.

The setup is simple: play a courier, take the job seriously or don't, and watch the city's slow slide toward something bad while you stock up on whatever advantages you can get. It's less about the letters and more about who you talk to, what you notice, and what you let slide while you're on the clock.

Structurally it runs as a sandbox with turn-based combat layered underneath the errand-running, so days are spent managing time between deliveries, preparation, and the people you cross paths with along the way. A separate system exists specifically to flag the story's more hidden netorare-related scenes so they don't slip past unnoticed, which tells you plainly what kind of game this is before you've read a single line of dialogue.

Changelog

v1.26
  • Bug fixes
v1.23
  • Bug fixes
v1.22
  • Correction of typographical errors
  • Bugfix
v1.12 - 2026-07-25
  • Bugfix
v1.12
  • Full release
v0.43
  • The update includes 8 new CG sets, with about 40 minutes to 1 hour of playtime. We’ve also added the Crystal Orb system to better visualize hidden NTR CGs in the story. However, since the recall scenes require much more time and fine-tuning, they were not able to be included in this update—my apologies for that.
  • Ver.0.43 will serve as the final preview version. From here on, development will shift toward building on the framework of the full version, which should allow progress to move much faster. Please note that all content in the current version is still not final—before release, there will be at least three more rounds of polishing and revisions. These will include not only additional detail work, but also ongoing improvements to sound, presentation, and translations.
v0.35
  • This version offers about 2 hours of gameplay.
  • After multiple rounds of testing and polish, we've completed the foundational system and core event framework.
  • That said, I personally feel it’s still not enough.
  • Future versions will continue expanding content and improving the gameplay experience, including:
  • Fast travel to herb gathering points and key locations
  • Streamlined pacing and improved controls
  • Due to time constraints, some of these features will be added gradually in future updates.
  • We appreciate your understanding and patience!
  • ✦ Highlights of Ver 0.35
  • This update establishes the core systems and world structure.
  • At the end of the prologue, the story branches into three main paths:
  • Dragon Route (Pure Love): A grand and gentle story arc, soon to dive into a “Prison” setting
  • Craig the Merchant Route: A corruption route set along a journey, featuring scenes on carriages, inns, and shadow shows
  • Muan the Blacksmith Route: A wild, desire-driven path set in campgrounds and the wilderness
  • Each route features unique maps, CGs, and custom events, providing a true divergence in gameplay.
  • In fact, thanks to player choices in the prologue, there are up to six path variations—some overlapping, others completely unique.
  • ✦ On Pacing & Narrative Direction
  • As a developer, creating this demo has been an intense challenge.
  • The prologue needed to present a believable world filled with tension, and plant key narrative seeds.
  • That’s why I poured so much effort into the story and event sequences.
  • Demo - v0.2
  • Fixed a bug where certain events would incorrectly teleport the player to the gallery
  • Fixed a bug where the village chief constantly showed an exclamation mark
  • Fixed tile display errors in the box-pushing area
  • Added a temporary option to remove the heroine from the party at rest points to prevent potential bugs
  • Demo - v0.2 Fix
  • This update adds 6 new CG sets and 5 events, all focused on Kare.
  • If you’ve already played Demo 0.1, simply download the new version to continue—no need to restart your save.
  • We’ve also fixed the bugs that were reported in Demo 0.1. However, some system optimizations and status display features are still pending. These will be addressed gradually during the development of the full version.
  • Demo - 0.1
  • Initial Release
