Seaside City is an adult sandbox dating sim focused on exploring a coastal metropolis, pursuing relationships, and uncovering a mystery connected to the family that takes the player in. It combines visual-novel-style storytelling with open-ended social gameplay, allowing choices about which characters and relationship paths to follow.
Exploring the city and its story hooks
The game opens with the player character leaving an orphanage to live at a luxurious estate. The hosts' shady connections establish the central mystery and provide a narrative reason to explore the surrounding city. Sandbox-style freedom allows story hooks and social opportunities to be found across the metropolitan setting, although the supplied information does not define a fixed sequence of locations or missions.
Choosing relationships and routes
More than 50 characters populate Seaside City. They are described as having distinct personalities, secrets, and potential romantic routes, giving the player choices about whom to pursue and whom to avoid. The branching structure supports different relationship outcomes and contributes to the game's stated replayability, but specific endings and route requirements are not documented.
Optional adult content and role choices
A flexible Dom/Sub mechanic affects dialogue and scene variations. This gives players control over the tone and direction of supported interactions. Sexual content, character routes, and specific kinks are optional, so players can decide which adult material and relationship paths to engage with. Because the game contains explicit adult content, it is intended for adults rather than minors.
Current state and planned additions
Version 0.1.2 is identified as the first version, with some routes and systems still incomplete and polish continuing. Planned development includes expanding the main story, adding characters, and progressing eight character routes: Cherry, Alice, Halley, Emily, a shared Sandy, Mandy, and Brandy route, plus three additional routes selected through a community poll.
Other planned features include an animated NSFW scene, an in-game phone, player inventory and interface elements, a morning, afternoon, and night cycle with time skipping, a strength system, updated interactable sprites, new locations and rooms, more music and sound effects, dynamic interface elements, bug fixes, and further optimization. These items are described as planned rather than confirmed current features.
