Lumbral

Lumbral is a puzzle of light and timing. Every level is a constellation: stars linked by threads of light. You tap a source to choose which beat it fires on. That's the whole game. No dragging, no long-presses, no menus to learn. A level is solved when every bell rings exactly once, on the same beat. Sounds simple. It isn't: mirrors echo everything downstream, gates only open when every pulse arrives together, and two pulses meeting head-on cancel each other out. Finding the right beat for every star is pure, quiet, addictive logic. 75 hand-designed levels across chapters, each introducing one new piece: · Source — fires on whichever beat you pick · Fixed source — same, but its beat is locked in · Node — relays the pulse down its other threads · Bell — the goal: rings once and absorbs the light · Mirror — sends the pulse back and doubles everything behind it · Gate — only opens when several pulses land together · Coil — holds a pulse for a few beats to even out paths · Damper — swallows the first pulse, then acts as a node · Void — anything that reaches it invalidates the solution No long tutorial, no extra text: every piece teaches itself as you play it. The first levels are free. A single purchase unlocks the rest — no subscriptions, no ads, no internet connection required, no data collected, period. Lumbral isn't in a hurry. Play five minutes on the couch or an hour chasing a whole chapter. Turn the volume up, tap the first star, and find the instant everything lights up together.
