What Is Mausoleosis?

David receives a frightened letter from his mother asking him to collect her. She has been dead for twenty years, but he enters the mausoleum where she was buried rather than ignore the message.

Story, Style, and Horror Design

RPG Maker pixel art gives the crypt an ornate, decaying identity. Rats, bones, music, and the impossible letter keep grief and supernatural dread intertwined.

Mausoleosis Tips

  • Save before decisions that change David's response.
  • Examine decorative objects; some carry puzzle context.
  • After one ending, change earlier choices instead of only the final action.
