What THANKS, LIGHT. is

You use light to turn flat silhouettes into solid objects, then absorb the light to flatten them again. THANKS, LIGHT. is a first-person puzzle game from the five-person South Korean studio Lightersgames. A shape you can step onto may need to become flat again to solve the next part of the room.

The same object can serve different jobs: weigh down a seesaw, stop a rolling ball or become part of a route. Mirrors duplicate objects, lenses change their size and shapes can be merged. The appeal is working out which state you need and when to switch it, rather than simply finding the right key.

Steam’s US listing currently says 14 October 2026. The official launch announcement says 15 October and explicitly notes that some regions display 14 October because of time zones. A free demo is linked on Steam. We have not played the final build.
