About the Game

Serment - Contract with a Devil (or Serment, for short) is a visual novel - dungeon crawler hybrid where you play as a girl who was revived by a beautiful devil.

Though, instead of claiming our heroine’s ever so cliche human soul, the devil demands a huge sum of money for payment. If the payment comes even one day late, the heroine's soul will return to the afterlife.

And so, her light-hearted, comedic adventure to save up enough money before the deadline begins.

Despite the dark sounding premise, the majority of Serment will be light-hearted slice of life events (more commonly known as cute girls doing cute things).

Game features:

  • Cute anime girls!
  • 4 playable main characters, each with their own unique story and endings.
  • More than 10 side characters, each with their own personalities and subplots.
  • A dungeon crawler with manually designed puzzles and 100+ unique items to discover!
  • A lot of cute anime girls!
  • Turn-based RPG battles with simple mechanics but tons of depth.
  • A detailed dating sim time management system.
  • Cooking, crafting and fishing minigames!
  • Light yuri (GxG) romance.
  • Steam Achievements and Trading Cards.
