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.
The game's innovative gameplay mechanic revolves around compatibility questions. During each date, players, in the role of the protagonist Gigachu, must answer a series of questions that test their compatibility with the Kaiju they are courting. The player's answers directly determine the strength of the relationship and the outcome of the date. This system requires players to closely observe each Kaiju's unique personality and preferences, and strategically apply that knowledge to progress the relationship.
One of the game's standout features is its diverse cast of Kaiju. Each Kaiju has a unique backstory, personality, and set of preferences, which are reflected in the specific compatibility questions they ask. Players must learn to understand and cater to the individual needs of each Kaiju, ensuring that each dating experience feels distinct and engaging.
The game offers a nonlinear gameplay experience, allowing players to freely explore the map and visit various landmarks to go on dates with the Kaiju of their choice. This open-ended approach gives players the freedom to approach the game in their preferred manner, fostering a sense of player agency and replayability.
The game's premise of Kaiju engaging in a "destructive courtship ritual" is a unique and compelling gameplay feature. As Gigachu, players can take their dates to famous landmarks around the world, where the Kaiju will engage in a playful, yet destructive, display of affection. This mechanic adds a layer of environmental interaction and visual spectacle to the dating sim experience.
The game's narrative is presented through the lens of two news anchors, who provide running commentary and analysis on the Kaiju's romantic exploits. This humorous and witty dialogue has been praised by many players, as it adds a charming and entertaining layer to the dating sim gameplay.
The game stands out for its inclusive approach to player customization, offering a range of pronoun options for the protagonist Gigachu. This level of inclusivity and player agency is a welcomed feature, allowing players to tailor the experience to their personal preferences.
