30 Days - Life With My Sister -v1.0- -pillowcase-

In v1.0, the protagonist has a hidden "Tension" stat. Sleeping on the same floor as Miki increases this stat. However, if you steal the PillowCase (which the game allows on Day 7, 14, and 21), the Tension stat resets, but Miki’s "Trust" stat becomes permanently locked at 50%. You can never achieve the "True Ending" if you touch the PillowCase without permission.

The PillowCase is embroidered with a faded kanji character—"Nostalgia" (懐). Clicking on the pillowcase during the free-roam segments (6:00 AM - 7:00 AM) triggers flashback sequences revealing why the siblings were separated. These flashbacks are only available in v1.0. Patch v1.1 moved them to a separate "Memories" menu, breaking immersion.

Veteran players argue that v1.0 is superior because of how it handles the "PillowCase" mechanic. In later versions, the pillowcase was demoted to a simple cosmetic item. But in -v1.0-, the PillowCase is a multi-functional game element: 30 Days - Life with My Sister -v1.0- -PillowCase-

Moving from early access or demo versions to a full v1.0 release can be rocky, but PillowCase has done an admirable job. The translation (assuming a localized release) is clean, free of the jarring grammar errors that often plague indie visual novels. I encountered no game-breaking bugs during my playthrough, and the patch notes indicate a healthy amount of community feedback was implemented before the final launch.

Depending on your actions with the PillowCase, 30 Days offers five distinct conclusions: Warning: The game contains no jump scares, but

Finding the original v1.0 is difficult. Most major distributors (Itch.io, Steam Greenlight) have delisted it due to the "Two Pillows Ending" and the non-consensual camera mechanic. However, the dev, known only as NekoNekoSoft_Retro, hosts the original .exe on a NeoCities archive.

System Requirements:

Warning: The game contains no jump scares, but it does contain prolonged silence, realistic depiction of financial anxiety, and a cat that may or may not exist (the "Ghost Cat" glitch in v1.0 is famous).
