CYAN PROJECT: Today, I Decided to Kidnap a Mermaid is a puzzle adventure set inside a near‑future research facility where secrecy, technology, and careful planning drive every step. You control Sei, a determined operator drawn into a complex mission to rescue the captive mermaid Sui. There is no combat or heavy action; the tension comes from deciphering intricate systems, navigating security measures, and uncovering the facility’s hidden layers through thoughtful exploration and careful timing.

Gameplay centers on solving puzzles rather than fighting. Progress unfolds by exploring connected rooms, collecting and using items at the right moments, and bypassing obstacles with clever resourcefulness. The design leans on escape‑room sensibilities: finding keys and tools, triggering mechanisms, and applying solutions in inventive ways to open new paths. Along the way you’ll encounter tile‑swap challenges and other brain‑teasing gimmicks that require you to rethink the layout and your approach to advance.

A crucial thread is Sui’s presence. Sui cannot stay on land for long, so you must plan routes with her constraints in mind while traversing the facility. Some puzzles demand mermaid‑specific interactions, meaning you’ll need to coordinate actions with Sui herself to unlock progress. Guiding Sui through each area becomes a core part of the puzzle, turning her mobility into a collaborative element rather than a solo obstacle.

The atmosphere blends a restrained, high‑tech setting with a sense of mystery and discovery. Expect moments of quiet observation, then focused bursts of problem solving as you uncover clues, reconfigure environments, and adapt to shifting situations. The variety of puzzles keeps the experience fresh—from item‑based exchanges to environmental re‑arrangements that alter how you move and think within the facility.

Replayability comes from branching outcomes. There are multiple endings that depend on how you progress through the story, the choices you make, and how effectively you coordinate with Sui. Your decisions shape the narrative arc and determine which conclusion you reach, inviting you to return with new strategies and a different approach to puzzle solving.

CYAN PROJECT provides smooth input support for both keyboard and controller, allowing you to tailor the feel of exploration to your preferred setup. If you enjoy thoughtful, non‑linear puzzles, precise planning, and a narrative that unfolds through clever problem solving rather than combat, this title offers a compact, immersive experience that challenges your mind and rewards careful, strategic thinking.
