For this game, all you need are these cards, a coin, a piece of paper, and something to write with.
Choices: When you are faced with a decision, read the card with the number corresponding to your choice. Sometimes you are not given a choice; at other times, the coin will choose for you.
HP & SP: On your piece of paper, note down your HP and SP (social points). Both begin at 0, and can go down to the negatives. Certain checkpoints will have pathways determined by your current HP and/or SP, and these gauges will also have an effect on your ending.
Endings: The game has 16 endings in total to collect. When you reach an ending, it will be noted on the card. After that, you may choose to start again from the beginning.
All in all, just follow the instructions and you’ll be fine. Good luck!
