A paper charm. A single step. A well-written spell brings the garden to life.

The Sigil Engine is a logic puzzle game about arranging spells. Instead of steering your shikigami directly, build a sequence on a scroll and watch it unfold: reach a lantern, gather mana, break an obstacle, or cleanse the ground at just the right moment.

No programming experience is needed. Actions, conditions and loops are visual spell tiles. The challenge is to read the garden and turn your idea into a working spell.

Five chapters. Five ways to think.

Explore 60 puzzles across five distinct garden settings:

- Learn movement, gathering, Blast, conditions, loops and Purify.

- Slide across ice and use obstacles to stop exactly where you need to.

- Trace portals and rethink distance, destinations and action order.

- Push stones while preserving the space you need for the next move.

- Switch red and blue phases to open sun and moon seals at the right time.

Make it work. Then make it elegant.

A misplaced action can send your shikigami into a wall. Review the steps, find the mistake and rewrite your scroll. Any successful solution lets you move on; use fewer lines and less energy to pursue a better rating.

Need a nudge? Reveal layered hints at your own pace. Hints never affect your rating.

Garden Watch: plan for the long night.

Gather, grow and cleanse in a garden that changes as you act. Spend your limited mana on energy or new spells. Every ten actions, upkeep is paid and the garden changes—your spell keeps running. Forecasts give you time to plan around incoming obstacles and optional, fleeting opportunities.

Choose a growth bonus every five rounds. Complete fifteen rounds to finish your watch, or carry on in endless mode. The garden may be peaceful, but surviving it takes preparation.

Moonlight, paper charms and quiet discoveries.

Purple-and-gold scrolls, warm lanterns and distinct chapter scenery accompany each experiment.
