Nyasha frames its puzzle play around spending time with a cast of young women while dealing with scattered pieces of their memories. The store description names Arizu and Megumi among the characters, alongside others, giving the game a character-focused premise rather than presenting its puzzles as an abstract challenge.
The core structure is explicit: players work through ten stages, with three difficulty levels shaping the puzzle experience. In-game help is available through the H key, and the listed features include artwork, music, Steam achievements and trading cards. Together, those details suggest a compact, stage-based puzzle design with supporting collectibles and assistance, without requiring assumptions about how individual puzzles operate.
Nyasha is categorized as single-player, so its play format is a solo puzzle experience rather than a shared-session game.
