Coloratura

Coloratura is one of the greatest sci-fi IF of all time. In this game, you play as a being utterly different from us that encounters a situation it has never experienced before.

The game has all of the usual commands, plus some new commands, the most interesting of which are color-based commands. Different colors signify different moods or ideas.

The puzzles are extremely rewarding, and fit into the plot exactly. The NPC's are well-implemented, and the nature of the game makes you feel as if the parser is not limiting conversation at all, only the world itself is.

I didn't really need a map for this game. It took a couple of hours to play. The game's biggest strength is its ability to put you in the shoes of someone completely different from you, to make you really feel like you are them.

I only wish the game had lasted a bit longer. But this may have made the puzzles less cohesive.
