This game was directly inspired by the Hard Puzzle games in its difficulty level and clarity and by Junior Arithmancer in its actual puzzles.
Hard Puzzle was mainly known for being intentionally poorly-clued, with numerous red herrings and puzzles that aren't quite fair. The idea was to have a kind of game you can beat your head against for a long time before finding a solution.
This game is similar. You find yourself in 4 rooms with a helpful fairy. Each room has a number on the floor and some other object of interest in the room (either a door or a clue). There is a recess that is common to all the rooms (essentially in the center of the circle) with a book.
Puzzles involve the book and the numbers and the clues (which makes sense, since that's all there is) and is similar to Junior Arithmancer a bit.
I found the game very unfair and very confusing, but that is the intent. I got a lot of help from the fairy (enough to solve one of the clues) but looked on the adrift forums for the other 2.
I wish I were able to type and execute a list of commands on one line, separated by punctuation. Once you know the answers to the puzzle, it can be pretty tedious to enter.
Overall:
+Descriptiveness: It's effective for the style it's going for
+Interactivity: I didn't like the tediousness, but the game was trying to be frustrating and hard, and it was
-Emotional impact: I saw this entirely as a puzzler, removed from emotional ties
+Polish: I encountered no bugs.
-Would I play again?: The value's all in the surprise, and there's not much replay value.
