Play Itsudemo Nyanto Wonderful Online

Itsudemo Nyanto Wonderful is a puzzle game released for the Game Boy in 1990 by TOSE. It arrived during the handheld's early years, a time when simple, clever concepts often defined the best portable experiences. The game doesn't try to be an epic; it's a focused and compact adventure built around a single, persistent mechanic.

You control a cat whose main objective is to capture all the mice on each single-screen stage. Your primary tool is blocks, which you can push to corral the scurrying mice or to block their escape routes. The puzzles quickly evolve beyond simple shoving, introducing elements like bouncing fish that must be ricocheted off walls to hit switches and open new paths. The pacing is deliberate, demanding careful planning as one wrong move can trap you, often requiring a reset. It feels like a constant, satisfying battle of wits against the level design itself.
