Metamorphoses

Not only is this one of Emily Short's best works ( along with bronze, check it out), but this is a sure candidate for one of the best adventures ever. The story was bleak to say the least, with just a few hints here and there, but it works wonders for the mysterious story. You know that you're a slave sent by your master for some mission, but you slowly accumulate the story as you go along. And yes, it's one heck of a story too. Brilliant characters, brilliant story, great puzzles and the philosophy was top.
The main character, a slave is relatively unknown except for the flashbacks we have in the game. The game though focuses more on the puzzles and the philosophy though than the character, but the little we do know bought the protagonist really strengthens the plot.
The puzzles are really neat in many ways. They fit the magic that you feel in the story, in the sense that none of the puzzles feel forced, but feel like they should be there. Also unlike many adventures, the puzzles are solvable in many different ways, so the game is repeatable. These puzzles are genius. However even with the 5 star rating, not everything was perfect. I found that two puzzles in particular (Spoiler - click to show)the oven and the ball were impossible if you did a small bit wrong. Ah well, I saved. In short though, the puzzles were fair.
On a side note, I loved the Plato mixed in with the story, well actually the main part of the story, aka. The 5th element. Makes me want to read Plato again.
