Note written 2026-09-15; the live figures above take precedence over any numbers in it.

Knock-knock is a 2013 psychological adventure from Ice-Pick Lodge about an insomniac visited by mysterious figures in a claustrophobic apartment.

This title sits in a rare pocket: strong retention (87% positive, 20% still playing), resilient residuals ($290/mo), and near-zero recent marketing spend, yet it has seen no discount promotions in over a year and no developer updates in nearly nine months. The game trades on Ice-Pick Lodge's cult reputation for surrealist horror and unique aesthetic, a studio with a loyal but narrow audience. For a publisher seeking dormant catalog depth or a studio wanting to understand how legacy indie titles sustain engagement without active promotion, Knock-knock merits a closer look; for mainstream revival, the unconventional tone and Russian developer context present real headwinds. Most realistic play: watch.

  • Risk: Niche psychedelic horror with Russian cultural DNA limits crossover appeal and mainstream marketing leverage.
  • Risk: No cloud save, workshop, or recent engine updates; aging codebase may face friction on modern OS variants.
  • Risk: Developer communication has stalled for nine months; unclear whether Ice-Pick Lodge intends active stewardship or is in quiet maintenance mode.
