Mature Content Description

The developers describe the content like this:

This game is intended for adults only and contains frequent depictions of explicit, uncensored sexual content and nudity. All characters depicted are fictional adults aged 18 or older (the three characters are stated in-game as 24, 24 and 22 years old).

Sexual content is presented within consensual, fictional adult relationships and is shown in the form of illustrated full-screen scenes with accompanying written text, unlocked and replayed from an in-game gallery. There is no depiction of non-consent, sexual violence, minors, real people, bestiality, or drug use.

About This Game

Three castaways, one tide line

Your flight goes down over open water and the tide puts you on a beach with nothing but the clothes on your back. You're not alone for long. Kai and Dana wash up the same morning, ten metres apart, arguing before they've even noticed you. Wren turns up later, deeper in the tree line, already unimpressed by the whole situation. Building a life on the island - and finding out what these three actually want from you - is the whole game.

How it plays

  • Swap adjacent tiles to line up 3 or more of the same kind. Bigger matches score bigger points and trigger chain reactions as new tiles drop in.

  • Limited moves, score targets: every level gives you a fixed budget of swaps to reach its target score. No timers - it's turn-based, think as long as you like.

  • 5 levels of rising difficulty: boards grow from 6x6 up to 8x7, tile types increase from 3 to 5, and move budgets shrink from 20 to 16. Later levels reward planning, not just spotting pairs.

  • Every level you clear unlocks new scenes. In the full game each of the 5 levels unlocks one new scene with each of the three castaways - 15 uncensored scenes in total, grouped in the gallery by girl.

  • Auto-saved progress: your level progress and unlocks are saved automatically, and every unlocked scene can be replayed from the gallery.

Your castaways

  • KAI - 24, a freediver who acts first and thinks about it later. Wet more often than not, on first-name terms with the local wildlife, and allergic to overthinking anything.

  • DANA - 24, Kai's twin sister down to the scar, and nothing like her otherwise. Plans everything, keeps lists, and is almost always right about it.

  • WREN - 22, dry, sarcastic, and dressed for a boat deck rather than a beach. Turns up partway through with a notebook full of poems and zero patience for the situation.

The scenes

Each unlocked scene is a full-screen, fully uncensored CG paired with a short written vignette in first person. Everything you've unlocked can be replayed at any time from the in-game gallery, organised in tabs by castaway.

What's included

  • 5 match-3 levels with escalating board sizes, tile types and score targets

  • 15 fully uncensored adult scenes, each with its own written vignette

  • Scene gallery with instant replay of everything you've unlocked

  • Automatic progress saving

  • Original music: menu theme, board theme and a level-clear jingle

  • Playtime: roughly 1-2 hours to clear all levels and see every scene, depending on your puzzle skill
