After dark, sealed places do not stay empty. Kaii Shutter is a top-down Japanese horror investigation game. You walk ruined interiors, recover ten scattered objects, keep out of the presence's way, and return to the entrance alive. You left a local paper. Families of the missing now send you after what remains. The leads point to four closed sites: an old housing block, a mountain inn, an abandoned school, and a hospital. You cannot fight what walks there. Hide, read sound and sight, and get out with the evidence. Play for free · Free Mode at the Showa Housing Block, exterior and interiors A / B / C · Ten evidence pieces that change with each new investigation · Move, inspect, hide, and escape as a complete loop One purchase, kept forever · Mountain Inn, Abandoned School, and Municipal Hospital, four areas each · Challenge Mode at all four locations · Fastest-time leaderboards per location Notes · Sixteen night interiors in a dry, hand-drawn matte look · Layout stays fixed during a run and rerolls on a new one · No combat: stealth, chase, and hiding only · Touch and game controllers · English, Japanese, Simplified Chinese, and Traditional Chinese · No ads and no consumable IAP The extra locations and Challenge Mode are a restorable one-time unlock. Not available in mainland China or Vietnam.

Verdict
The clearest difference is ads: Kaii Shutter at none against Polyescape's shown. Kaii Shutter also leads on update cadence (every 2 days vs every 5 months). Polyescape's advantage is iOS requirement (15.6 vs 17.0). On price, in-app purchases and device support there is nothing between them.
