The story is weaved together nicely. It starts off very gently, just giving you a few clues and then you get the bigger picture. Even though there's a lot of supernatural elements in the game, it was done in such a way it didn't make the characters feel out of place. Nina is as a young woman who has no superpowers, but is pulled into a mystery where she must confront these strange things. It makes you relate to her and her own worries.
I found the story very good. It kept me interested and wanted me to really finish the game. The game makes you travel to many different areas in the world. I liked the change of environment and due to the complicated story, it also makes sense as to why Nina would travel all these areas without it feeling out of place. The new places allows for lots of exploring on it's own and are not confined to a few areas.
Finding out the clues are mostly not that difficult. There are some very clever clues, like needing to look at paintings and see what it represents in numbers to open up a safe. There are some objects in the game which are annoyingly tiny on the screen, as you see each area and room from quite a distance. It can be quite annoying when you have to click on an itty bitty edge of a carpet, as the pointer doesn't register unless you are close enough to the specific area. Thankfully there aren't a lot of these.
The game is good at providing ideas of what to do next. Nina will make comments about her environment and gives good clues about how to solve things. It doesn't spoil anything or leave it too easy, just enough to make you think things through. At one point, Nina reads a poem which indicates what items she needs, masked though the words. At some points in the game, you have two characters to control. This is a great idea which works out very well, you swap between them in the same area, so that they can complete things in different parts of the building. Clever use of mechanics and storytelling.
I admit, sometimes I got very frustrated as I knew what I wanted to do, yet the characters kept complaning they couldn't, despite needing the item. Sometimes you have to prepare a lot of other things before you can use the idea first at hand. At one part, Nina needs to climb an area which she does awfully slow, then if you forget an item or need to go back and try something else, she will slowly get back the same way. Going back and forth between these two could be very tedious, but thankfully they shorten the time you have to watch it, to not waste time.
The mini-games weren't annoyingly complicated, they were difficult enough to manage on my own without having to look at some guide. One of them is pushing lighted buttons until all lights are out, and certain buttons only turn off or light certain lights. There aren't a lot of these, thankfully,
There is some funny dialogue at times, which lightens the mood when you're stuck for a while figuring things out. Nina will usually make quirky or sarcastic comments about the items she tries using or the situations she has been in.
The english voicework isn't really that enjoyable, so I wish they could have had an option for the original german voice acting. Nina's voice is in particular very straining for the ears. I can tolerate her voice due to the dialogue being fun at times. I don't know what it is about her voice that bothers me, but I think it is the fact that I couldn't honestly tell how old Nina is supposed to be. She sounds like she is 10, but she looks like she's about 17. Her voice just sounds really childish.
Overall, I enjoyed this game and piecing the story together. Even though the ending is a bit over the top. There are some nice cutscenes in the game and the ending credits features what happened to all the characters after the game ends. Some are very funny to read.
