As you can see with the rather corny title, this game had a really good impact on me. At first, I had no idea what I was getting myself into with severed arms groping around over the rocks, and was furthermore confused with "her". Was she a monster? A godess? A spirit? As I got further and further into the game, it all made so much more sense.
The beginning of the game consists of you (or us) running around trying to figure out what the heck is going on. It is evadent that something is invading your home, and you have to stop it by using your powers and changing from object to object to solve the puzzle. This I think is the charm and attraction to the game. Like a good mystery story, you start with no knowledge of what's going on, and slowly gather information before *boom* this is what's happening! It's the mysterious way the author writes which makes the story attracting. The perspective of the character (well, character-s if you want to get technical) is very primitive but really thoughtful. (Spoiler - click to show) for example, the gun is to you just a metal rod with swirling energy. legion, is one of the best mysterious writing in IF and has such unique characteristics.
Puzzles in the game are fairly straightforward. At the beginning, the puzzles especially are designed to ease you into the story, which is nice because the style is alien. After, this though, expect slightly more difficult puzzles say low-medium. Most of the puzzles involve touching objects, and transferring from one object to another to get a better advantage, but there are all sorts involved. The sudden flashbacks were confusing and appear extraneous, but in the end are quite revealing. The puzzles really are briliant, and I'd love to say much more why I love them, but I would hate to spoil completely this well crafted gem. I will say that I enjoyed the many multiple endings that there were letting you try to find as many possible.
Although there are some annoyances which make the game a little bumpy, this game is amazing.
