Indie Game Review | By A. N. Other
Released as a completed v1.0 build under the suggestive “PillowCase” label, 30 Days - Life with My Sister is a narrative-driven simulation game that has garnered attention for its domestic setting, branching choices, and the controversial premise its title implies. However, beneath the surface-level assumptions lies a more nuanced experience that focuses heavily on routine, consequence, and the reconstruction of a strained sibling relationship.
With v1.0, the game offers 12 distinct endings, ranging from “Distant Strangers” (moving out without a word) to “Reconciled Kin” (attending each other’s future weddings as best friends). The “True Ending” requires a perfect balance of respect and routine, unlocking a final diary entry that reframes the entire 30-day experiment as a form of prescribed therapy.
Replay value is high, as a single playthrough takes roughly 2-3 real hours. However, the lack of a skip-read dialogue option for already-seen text is a notable oversight in this build.
Depending on your actions with the PillowCase, 30 Days offers five distinct conclusions:
As a Kinetic Novel (or a light Visual Novel with branching paths), the gameplay is minimalistic.

If you’d like me to tweak the tone (make it more hype-focused or more technical) or if you need help finding specific walkthrough steps for the new v1.0 content, just let me know!
The core loop is deceptively simple: each day is divided into four segments (Morning, Afternoon, Evening, Late Night). The player must allocate time to:
Where 30 Days shines is its consequence system. Unlike many dating or life sims, ignoring your sister leads to a cold, silent house, but over engaging triggers a “Pressure” meter. The game punishes obsessive behavior, encouraging a balanced, healthy cohabitation rather than a forced romance.
The game strips away any complex fantasy or sci-fi mechanics in favor of a mundane, ticking clock. You play as a protagonist who has returned to a shared family home, tasked with cohabitating with his sister for exactly 30 in-game days. The “v1.0” stamp indicates that all core systems—time management, dialogue trees, and the relationship meter—are fully implemented and bug-free, a notable achievement for a niche indie project.
The subtitle, -PillowCase-, serves as a version or content warning tag, signaling that while the game is not explicitly explicit, it deals with themes of intimacy, personal boundaries, and emotional vulnerability, often during late-night or early-morning “room” segments.
