Metamorphoses

You're a slave girl on a mission of sorts for your master, though it's difficult to say what the mission is. The game's world is split between the literal and the figurative, and most of what you accomplish is significant more on the symbolic than on the concrete level. Idealized forms are a key thematic element, and most of the puzzles revolve around the transformation of those forms. The game provides two devices that can transform various objects, and the range and complexity of the transformations handled is impressive--the objects, by and large, behave sensibly in all their various forms.

There are lots of puzzle solutions and a wide variety of endings, and the game manages to both tell a story and allow ample freedom in exploration. Beautifully described and impressively thoughtful.
