About this game

filament is a calm occupy-to-win puzzle: fill every cell with your coil or embers.

HOW TO PLAY
• Swipe to turn. Hold to brake (and cool heat).
• Sparks grow the coil and raise heat.
• Stamps shrink you and leave walkable embers — your fill.
• Cover the whole grid to Occupy and save a Glyph.

PRO (optional one-time unlock)
Themes, coil colours, and modes: Twin Spark, Ghost, Ash, Decay, Walls, Bloom, Scarce — plus challenges.

Also optional: Google Play Games achievements and leaderboards, and a local daily Glyph reminder (off by default).

No ads. Built for short, focused runs.
Occupy the grid. Grow on Sparks, claim space with Stamps. One clean puzzle.
