Lefto Studio and publisher TARK released BOMBANANA! on Steam on September 2, 2026. The three-player cooperative puzzle game assigns each player one of the three wise monkeys, each with a different sensory restriction. See-no-evil can touch the bomb but cannot see wire colors or module symbols. Speak-no-evil holds the defusal manual and knows the answers but cannot speak or use in-game chat, communicating only through gestures and emotes. Hear-no-evil can see the bomb and both teammates but cannot hear anything. Players must defuse bombs within a time limit despite the miscommunication. The game ships with a Campaign mode of 30 stages, an Endless mode with auto-generated bombs, and a Custom mode for designing original stages. Stage gimmicks include power outages, obstacles, and noise interference. The demo, released during Steam Next Fest June 2026, was played by 6 million users and was the most played game at the event. The full version costs 1,050 yen, with a launch discount running until September 10.
Players coordinate through pointing, hand waving, and gestures, and can also slap teammates or flip them off. The demo was set inside a minivan, while the full version suggests bombs can also be defused on an airplane. Each bomb carries modules with different rules, and clearing stages unlocks higher-difficulty bombs through a level system that raises difficulty as it progresses. Gimmicks such as blackouts, obstacles, and loud noise interference complicate defusal.
Wishlist registrations have exceeded 1 million, one outlet reports. The game supports Japanese and offers public lobbies for playing with people worldwide. The three outlets disagree on pricing: one lists 1,050 yen with a 20 percent launch discount, another lists a 38 percent discount running until September 10, and a third says the price was undecided at the time of writing. One outlet also notes the demo was the second most played demo across all of Steam. Players must defuse bombs within a time limit, and miscommunication between the three roles is the core challenge.
