This is basically a point and click adventure with beautiful environments, a nice ost and an interesting lore behind it.
There are some big flaws though. For start the opening of the story is pretty intriguing, but the game starts with a time skip and you feel really lost. There's a lot of lore behind it, but never expands into something actually interesting except the very ending.
The gameplay is also pretty frustrating. You get all of these items with sci-fi jargon descriptions that you're not exactly sure what they do, so your only option is to use them on everything in hope they interact with something.
Also there are a lot of fetch quests where you have to go to the other side of the map to get something and come back again.
There is also an arena where you fight with various creatures in turn based battles. I think I read that they add it later to tackle complaints for the lack of combat (why would an adventure have combat in the first place is beyond me), but it's completely unnecessary and a waste of dev time.

Even with all these flaws I would still recommend it. There's something relaxing about it and the pre-rendered backgrounds are drop dead gorgeous.
