Warning: This game contains mature content. Not suitable for minors. Play at your own discretion.

This version strengthens the emotional pull, better highlights the non-commercial aspect (which is crucial for trust), and ensures the mature content warning is both clear and prominent—without overshadowing the game’s artistic and narrative strengths.

If you're planning to publish this on itch.io, Steam, or a similar platform, consider adding:

• A short, evocative tagline (e.g., "The truth lies beneath. The danger lies above.")
• Optional age rating or content advisory badges.
• A teaser video or audio clip of the vault’s ambient sounds.
