Synthesized from 11 Yomimono stories · updated Oct 10

BOMBANANA began as a Steam demo during June 2026's Steam Next Fest and became a full release on September 2. Lefto Studio, based in Beykoz, Turkey, built the three-player co-op bomb defusal game around the three wise monkeys motif. Each player controls one monkey with a different sensory restriction: one can touch the bomb but sees only outlines, one reads the defusal manual but cannot speak and must use gestures, and one observes the bomb and surroundings but cannot hear any audio.

The demo drew 6 million players and topped the event as the most played title. By launch, wishlists had passed 1 million. The full version added a Campaign mode with 30 stages, an Endless mode with auto-generated bombs, a Custom mode for designing original stages, 14 new modules, and a slap feature.

Sales moved quickly. The game passed 500,000 copies in under a week and 1 million copies within 10 days. Steam reviews have held an Overwhelmingly Positive rating, with 96 percent of over 2,700 reviews positive at the 1 million mark. Twitch concurrent viewers peaked at 90,000, and the developer, Ufuk Girit, cited Keep Talking and Nobody Explodes and a viral YouTube video as influences.

Lefto Studio and publisher TARK have since announced mobile and console plans for October. The game remains available for PC and Mac at 1,050 yen with Japanese language support.
