The game is a 2D side scroller where you can create clones of yourself which mimic your movement and you can also swap into those clones to solve puzzles with switches and pressure plates to find out what happened on a derelectic space station stranded on a planet. Fitting to the central mechanic is also a bit philosophy about what is the mind etc. involved, but not as explicit as in Soma.
The puzzles are not so convoluted that you don’t understand what you need to do, but also not so easy that it’s just busywork. The art style is a bit different, because they modelled everything in clay and then digitized it, leading to a pretty unique style. Together with the sparse lightning it creates a wonderful eery atmosphere in the space station. The story plays into this atmosphere, but it is not the main focus of the game. Still, I found a certain philosophical concept they introduced fascinating, because I never thought about it.

Namely, the concept of minds without senses and the concept of the great chain they developed out of this. In the middle of the game you learn that the planet is not without life at all. But it is life in the form of rocks that don’t have any sensory organs but are telepathic in their surrounding area. Which means they don’t have any feeling for where the other rocks are, but just that they can speak with some and don’t speak with a lot of others. But in a long chain they can speak over vast distances. When they are taken for studying by the humans, they realize that they got cut off from that great chain and wonder what could be the reason. Only later do they find out it was done by another life form, us humans. And we exemplify completely alien concepts to them: none telepathic and apparently able to interact with something called “space”.
So all in all it is a fun little game of around 5h with a little bit of philosophical concepts if you want to think about it or just some neat puzzles and atmosphere if you don’t.
Ratchet and clank had a similar mechanic. Think it was a Crack in Time or something like that.
