v0.05.0 - 2026-01-22
What's new:
— New story content
Complete Operation "Zone of Silence" by resolving the dilemma and meet the new hybrid, who may become a romantic interest in the future.
— Two new sex scenes with Melisa (not optional) and Siena (optional)
(finally, a sex update!)
— Fixed some text and dialogue errors
— Most images have been converted to WebP format to save space

⚠Attention!⚠
I've received reports that the game becomes unstable when running with mods
(confirmed case with KoGa3's mod). Issues may include text errors,
duplicated sentences, and technical bugs. This is likely related to the
code of one of the features I implemented earlier, but unfortunately, I currently don't know how to fix it.
Therefore, please play without mods for a better gaming experience. And sorry for the inconvenience.

v0.02.1
— Improved Dialogue and Texts
The in-game dialogue has been refined for more fluent English, and narration has been given a more literary tone, enhancing the overall narrative and immersion.
— Bug Fixes
Resolved the quirky issue where the main character (MC) referred to Elina as his sister, even when she was chosen as a childhood friend. Improved the scene advancement buttons in the rest segments. Now, they are more responsive, being activated by clicking on any part of them.
— New Menu System
Introducing a streamlined and intuitive menu system to enrich your interaction with characters and objects during certain scenes. Look out for the eye icon in the upper right corner of your screen. When hovered over, interactive characters will be highlighted with an outline. We plan to add a hint or a small tutorial on how to use this new feature in a future update.
— Secrets
Divedeeper into the lore of our world with optional interactive objects. These secrets, indicated by a sparkle next to items, enrich the narrative and provide insights into other characters. Currently, one secret is available in the first rest scene with the MC squad. Stay tuned for more in upcoming updates!
— Dialogue System
Updated to make conversations feel more realistic and engaging. Selected dialogue options now disappear when returning to the choice, preventing repetitive dialogues.
— Visual Enhancements
Refined various visual elements for a more cohesive and appealing aesthetic.
— Performance Optimizations
Under-the-hood improvements for smoother gameplay and enhanced stability.

v0.02:
— at the beginning of the game added the ability to choose who will be Elina to the MC - sister or childhood friend. If you played 0.01, by default she should remain as a sister so the old saves should not conflict with new code lines.

— better textures for the HOWL squad uniform (only for MC for now)
— new main menu
— grammar corrections
— added Patreon link

v0.01:
— 130 renders
