Light Grid Logic
A Lights Out puzzle. Tap a bulb to toggle it and its four orthogonal neighbours; turn the whole grid off to clear the board. Order doesn't matter — parity does, so it's about which cells you press, not when. Undo and reset any time, and chase par (the number of presses the level was built from).

LUMINA — One-Thumb Arcade
LUMINA is a warm-light one-thumb arcade game. You are a beacon of light in the void — tap to emit a purifying light pulse that destroys incoming voidlings before they darken your core. Features 4 enemy types (fissure, wraith, shrouded, rift), chain combo scoring with precision proximity bonuses, a RADIANCE screen-clearing blast, escalating waves, and local high-score persistence. Gold/amber neon aesthetic on deep space.
AINA
A fine-art light puzzle in a mirror palace at night. Tap to set silvered mirror tesserae on the diagonal and bend a warm candle's beam through the hall until every glass lamp is lit. Twelve chambers across three chapters — the Antechamber, the Court of Mirrors, and the Dome of Light — introduce amber, rose and jade beams, fixed mirrors and carved columns, up to a six-lamp finale. A deterministic beam tracer makes the title screen a live āina-kāri demo on the real renderer, and a Hall of Mirrors remembers every chamber you light. Portrait-first, pure JavaScript, no build.

HELIOGRAPH — Signals Across the Iron Valleys
The line went dead at Cold Hollow and you are the new signal-keeper. Turn brass mirrors to walk a beam of sunlight across a hand-drawn valley and into the receiving station — then learn to split white light through a prism into three colours for three valleys, to husband a beam through fog that drains it, and to arrive on the beat while army shutters open and close. Twenty-four stations across five chapters, every one machine-proved solvable, with an honest par and a quiet score of plucked strings and glass bells.
