Antonio Route Play Guide

⚠️ Content Warning

This update contains strong adult themes which may be disturbing to some players, including but not limited to:

  • Violence and crime depictions

  • Sexual violence and suggestive content

  • Religious horror imagery

  • Shocking visual and audio effects

  • Ethical controversies

  • Moral dilemmas and depictions of human darkness

👉 This game is not recommended for minors. Please carefully consider your personal comfort level before playing.


Playtime & Recommendation

  • Reaching any ending in Antonio’s route takes about 20 hours.

  • Completing all endings takes about 25 hours.

  • Since the game is still in Early Access, after this major update we strongly recommend resetting your game from the main menu settings and starting again from Chapter One. (This will reset all collected progress.)


Story Experience & Hints

Reaching a final ending means you have made the right choices through every scheme and act of malice, and successfully inherited the legacy.

In this story:

  • You are not a detective, and no one will solve the mysteries for you.

  • Every ending and every stamp contains fragments of truth.

  • If you enjoy reviewing details and connecting clues across different routes, you will eventually clear the fog and uncover reality.


Mild Spoiler Guidance

  • Antonio’s secrets are tied to the endings “The Sister”, “The One”, and “Pugno”.

  • The truth behind the school’s mysteries is hidden in the two secret endings, and unlocking the stamp “The Truth Revealed” will also provide vital clues.

  • How to unlock “The Truth Revealed”: You must discover a certain secret about Solomon in Chapter Four, then meet Mrs. Merrick again in the ending “The Successor”.

  • In the endings “The Sister” and one hidden route, you will reunite with an unexpected character who brings further secrets and unresolved threads—these will be addressed in the upcoming Mika route.
