Some doors need more hands than you have. Lumen is an atmospheric puzzle game set in a chamber that does not let go. You carry the only light. Ahead of you: doors that will not stay open, plates that need weight you cannot spare, and a way out that always seems to need one more person than you brought. But you are not the only one here. Every time the light fails, something remains — a pale shape that walks the path you already walked, holding the doors you already opened. Learn to leave the right shapes in the right places, and the chamber begins to yield. Learn to leave the wrong ones, and it closes around you. ----------------------- ◆ FIFTY CHAMBERS Hand-built puzzles that grow from a single quiet room into six-way convergences where every step has to be accounted for. Nothing is random. Nothing is filler. ◆ NOTHING TO OUTRUN The cycle runs down and simply begins again — and everything you did stays behind to help. You never lose for being slow. You lose for planning it wrong. ◆ THINGS THAT DO NOT LAST Some of what you leave behind begins to fade. Some passages only go one way. Some floors are not safe to stand on. Each chamber teaches you one new rule, then asks you to live with it. ◆ MADE TO BE FINISHED No lives. No energy meters. No waiting to play. Every puzzle is solvable from the moment you see it — if you can see it. ◆ PLAYS ANYWHERE Fully offline. No account, no sign-up, nothing to connect. Just you, the lantern, and the dark. ----------------------- Tap a tile to walk. Reach the light. Simple to hold. Difficult to put down. Help yourself escape.

The stars are already on the grid. Connect the ones that belong to the same constellation. The number on each row and column counts main stars, not every star in that line. In a constellation, the main star is the one at the top-left. After you connect them, the main star stays the same size. The others shrink. You work from the numbers. It feels like a logic puzzle. It is not Sudoku, and the shape is not given in advance.
