Closure is a 2D platform puzzle game, where everything that has light on it exists. Everything that doesn't have lights will make you fall down. If you fall down to the bottom of the screen you will die. That sounds really simple as a mechanic, but is really well executed in the game. With a great look at detail. The thing you have to do is in every level is that you have to open a door to get to the next level. So you for instance have to find a key or get some object activated to open the door. You will be really challenged by many of puzzles. Some puzzles also got me really stuck for a while. What I like in the levels are the many different puzzles with new objects. The design and the sounddesign combine well within the game, working well with the game's aesthetics. The only bad thing I can say about the game was that at the third stage of the game the puzzles where strangely enough really easy. When compared to the stages before that. (Maybe it was just me.) Closure is instead of many other puzzle games I experienced, packed with many hours of gameplay. (12 hours )
Closure is also one of the few games that convinced me to replay some levels over again to get all the collectables. Which is challenging.
In short: A puzzle game with many hours of play where only anything in the light exists.
