Closure is a black and white alienish platform puzzle game where the world exists because of light. Without light, there is only nothing and I mean nothing, if you try to jump onto a platform that doesn’t have light near it, you will fall through the world. If you are swimming and your light floats away, you will drop out of the world without it. Solid walls become jumps when there is no light on them. The object of each of the almost 100 levels is basically to make it to the door at the end. You can pick up lit orbs, you can put lit orbs into carriers that will carry them. This leads to some really interesting platform mechanics, such as moving lights turn into elevators when normally they’d be solid walls. You can put orbs into transporters that will make 2 areas lit instead of 1. There are push boxes, push rollers that will of course roll, lit push boxes, lamps that you can adjust to cast light onto different areas and so on. This is a unique, enjoyable, atmospheric, immerse game, but I have a feeling that once you’re done, you’re done. They made a really alien world here and the music is awesome and belongs in a suspense drama. After the tutorial levels when the game opens up, the music eases up so its not as intense. Very worth a play through, I own it a few different ways, Steam, GOG, did I mention its free for Playstation Plus members?
