Don't Go In
Tap to step forward through a pitch-black corridor; with each step a new VHS-frame of the haunted house appears — stop, and the frame bleeds into the next room.
Tap to advance one corridor tile; long-hold to peek ahead in the dark for a clue, but holding too long summons the figure.
Tap to step, hold to peek (one thumb).
SELVEMA II's unraveling house where every room 'feels wrong' and corridors shift.
Reviews praise SELVEMA II's atmospheric shifts and 'rooms that feel wrong' — a tile-by-tile tile-walker translates that tension to one-thumb horror.
Tap-to-advance-into-darkness + risky peek is a clean tension loop, but the mechanic closely mirrors existing 'don't move / hold to peek' jump-scare apps, making it derivative rather than standout.

One-thumb tap/hold input, 2D tile grid, static frames — no physics, no 3D, no procedural art; trivially prototype-able in a weekend.

VHS/found-footage horror is visibly crowded on itch.io (Night of the Nun, The Tape, Babysitter Bloodbath, Last Order, Paranormal VHS, Power Drill Massacre all listed), and 'tap-to-advance corridor + jump scare' already has analogues (Momo-style apps, 'Who's at the Door?'), leaving little white space for a tile-walker twist.Indie VHS-style horror games already being showcased on TikTok — category is busy ↗
