Concept

Mosswake is a small, calm puzzle game. You guide a living moss colony across crumbling ruins, spreading it through cracks, shade and moisture to restore each ruin to a garden.

Core loop

1. Inspect a ruin grid with stone, water, sun and shade tiles.
2. Place a limited number of spores and rain seeds.
3. Press Grow. Moss spreads deterministically each tick by cellular-automaton rules: it needs moisture, dies in full sun, and can't cross bare stone without a crack.
4. Cover the target percentage of tiles to restore the ruin and earn stars for using fewer spores.

Platform and style

• Platform: browser (HTML5 canvas or TypeScript), mobile-friendly, no backend.
• Art: soft watercolor palette, hand-drawn stone, gentle ambient audio.

Minimum viable feature set

• Grid engine with deterministic tick rules.
• 12 hand-authored levels, undo and reset.
• Star scoring, local-storage progress, short tutorial.
