Closure is a full version puzzle and action game developed by Eyebrow Interactive for Windows. The game is based on the gameplay and plot of the game with light. The player takes on the role of a small man who is in almost total darkness. A spot of light snatches from the darkness, a small part in which the little man can move. The space for movement is limited by a spot of light, but sometimes, outside of this spot or on the border of light and darkness, it is possible to move quite freely.

The game consists of various obstacles that block the player's path, and the player needs to find the final exit. The puzzles involve searching for keys and finding ways to apply them, moving light sources, and many other things. The game requires the player to master the relationship with light and use this understanding to achieve the ultimate goal. The game is a perfect combination of puzzle and platformer, making it a thrilling experience for gamers.
