The story is not very deep, but it might help to keep you engaged. The puzzles involve bit of jumping and some looking around, but mostly they requirethinking which is great. I really like how the game is structured. I wish it was bit longer, but that is what I wish for Portal too:) Overall it is very similar to Portal, only you use magnetism instead of portals. And your main enemy is not as talkative as GlaDOS. and there is no cake:) I have finally managed to get all the achievements, and I must say that the game gets whole nedw level of difficulty when you have to avoid death, yet it is also way more rewarding when you succeed. The game looks great. It is not the best graphics there is, but the artistic feel is really good, and I wish more games could do something similar to the Act III of this game.
