Kaichu is a dating sim about kaiju! You play the role of Gigachu, a gigantic romantic looking for love. Meet 6 other eligible kaiju and visit 24 famous landmarks where Gigachu will answer challenging compatibility questions to decide the fate of your relationship.
During each date, players must answer a series of compatibility questions to determine the fate of their relationship with the kaiju they are courting. These questions are based on the individual kaiju's personality and preferences, requiring players to learn and apply their knowledge about each kaiju to progress the story. This quiz-style approach adds an engaging, interactive element that sets the game apart from traditional dating sims.
The game offers an open, nonlinear experience, allowing players to freely explore the map and date any of the six lovable kaiju from the start. Each kaiju has their own unique storyline and relationship obstacles, providing multiple playthroughs and narrative paths for players to discover their personal favorite kaiju and pursue their desired romantic outcomes.
The core mechanic revolves around the kaiju's destructive courtship rituals. During dates, the kaiju will prompt the player character, Gigachu, with compatibility questions. Depending on how well the player's answers match the kaiju's preferences, the relationship will either grow stronger or weaker. This intimate, yet chaotic, courtship dance is a key part of the gameplay that players find both amusing and engaging.
The hand-painted backgrounds and hand-animated kaiju characters are praised for their beauty and charm, capturing the personality of the giant monsters. The destruction of iconic landmarks during the dates is vividly portrayed, with players delighting in the spectacle of these kaiju crushfests.
While the mechanics are simple, with players primarily choosing from multiple-choice options, the short duration of each date, combined with the light-hearted tone and cute aesthetics, make the gameplay loop an enjoyable, bite-sized experience that doesn't overstay its welcome.
