Development Update: Ver0.43 Coming Soon!

Hello everyone, this is LactoQuest.

On top of that, we’ve carefully adjusted some of the CGs based on your valuable feedback, ensuring that the overall style remains consistent.

I’m very happy to announce that Ver0.43 is scheduled for release at the end of this month!

Her Fall in the Last Days: Gaiden Development Update

Hello everyone, this is LactoQuest.

I am currently focusing on the development of Her Fall in the Last Days: Gaiden.
As for Stigma of Corruption: Nightbound Courier, we are still in the process of searching for a suitable illustrator. Development is continuing, but until we find the right partner, I will be putting more effort into the production of the Gaiden.

Thank you very much for your constant support. I strongly believe that only by working harder and de...

Regarding Development Progress and Compensation

Hello everyone, this is LactoQuest.

I regret to inform you that, due to certain circumstances, my collaboration with illustrator Mao has come to an end. Unfortunately, I am unable to fully carry on the existing art style by myself. This means that CG production will be temporarily suspended, which will also cause delays in the overall development progress.

However, please rest assured that the story and gameplay development will continue as planned. At the same time, I have alread...

Early previews of CGs and their scrapped versions

The carriage CG has finally been completed!
This scene will appear in the latter half of the “Hawkpeak Fortress” chapter.

We’ll also be sharing a previously scrapped carriage CG.
Although we were quite fond of that version as well, it had to be cut due to changes in direction and scene composition. It’s a shame, really—the quality was great.

We hope you enjoy both versions, each with its own unique atmosphere!

Early Preview of Side Story & New CGs 4

Here are some recent drafts. I'm sorry for not updating on Patreon lately. Last mon, my account was reported because I included NSFW images in a public post, which resulted in some temporary restrictions. Things have improved since then, but I can no longer share explicit content in public posts.

I expect to finish the content for the 0.3 update within the next couple of days. However, considering the time needed for translation and testing, the new version will be released on the 15th....

[Demo 0.2 Bug Fix Report]

Thank you all for your continued support and feedback. I've fixed the following issues based on recent reports:

• 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

Dev Log – Preparing Stories

Hello everyone, this is LactoQuest.

It’s time once again for a development update.

Since the last post, I have to admit that overall progress has been a bit stagnant. This past week, I’ve been focused mainly on foundational tasks—preparing new character busts, pixel sprites, some pixel animations, and various base assets. Although the game itself hasn’t moved forward much, I’m still confident that I’ll be able to push out an update by the end of this month.
