Gameplay instructions
SecondBrain is a Game Boy-style narrative game that runs in the browser. No installation or account is needed.

HOW TO PLAY
1. Open the game page and start the game. Choose your language: English, 日本語 or 中文.
2. Move Yuki with the arrow keys (or the on-screen D-pad). Walk up to people and objects and press [CONFIRM KEY] to talk or interact.
3. Read the dialogue and press [CONFIRM KEY] to advance. When a choice appears, pick an answer with the arrow keys. Your choices shape which memories, emotions and Zen sayings you collect.
4. Play through the chapters in order: an ordinary life, the mountains through four seasons, the Zen room, and meditation on the grassland.

THERE IS NO WAY TO FAIL
There is no timer, no combat and no game over. Take the game at your own pace.

OPTIONAL MODES
- Read-aloud mode: the game narrates the story by voice, so it can be played without looking at the screen.
- Emotion encyclopedia: review the emotions you have collected (75 in total) and 30 Zen sayings.
- Daily sudoku: a new puzzle every day, played with the same controls.

AFTER CHAPTER 5: CREATE YOUR OWN CHAPTER
The game does not end at Chapter 5. After finishing it, players can build their own content with the same method used to make SecondBrain.

The method is packaged as an AI skill: a methodology for building Game Boy-style (160×144, four-tone green) narrative games that ship entirely in a single offline HTML file. Art, chiptune audio, story, maps and the save system are all included, with no engine and no external dependencies. It gives creators a tested path from a reference image to an itch.io release, covering architecture principles, the art-to-pixel pipeline, procedural chiptune audio, a three-layer testing workflow, and publishing.
