Of course, this game is very well written, and there is a lot of findings and innovative ideas, even two imaginary languages have been created, making the gameplay quite unique. There are some humorous comments, there are parts which are very realistic while others are oniric (and sometimes absurd).
Nevertheless, the game greatly suffers from the fact that it is extremely difficult, requiring the help from a walkthrough, and absolutely unfair to the player, up to the point that the author seems to have forgotten that a game (or a novel, or whatever) must not be done for oneself but for others to enjoy. Let me sum up the weakpoints:
* too many puzzles are of the "guess-the-verb" type. Sometimes the verb is common, but the action is absurd. Some examples are (Spoiler - click to show)go port, say time, say yellow, turn noise, tighten the skull, push cat to, jump, wave branch, blow whistle, "hole,!go west", etc
* the command "look at" is poorly implemented ("you see nothing special about...") where it could have been used to give a small hint to the player and make the game a lot more enjoyable. This is also the case for other commands and objects, as explained in another review of this game on this website.
* the order in which you visit locations is vital. If you visit them in the wrong order you can get stuck without knowing it! The problem is that you are not allowed to teleport twice to the same location using the device (Spoiler - click to show)the projector using cards, so you are not free to explore, and guess the solution by some trial-and-error. And there are no clue of what is the right order, or the clues are very obscure.
* some objects are absolutely mandatory to finish the game, but these objects must also be magically converted at some point to other objects(Spoiler - click to show)(rods). The problem is that they can not be converted back, so you get stuck long after having wrongly converted the object, thinking doing right, with the only option to restore a previous saved game.
In conclusion, unless you like twisted and cruel games, and don't bother saving/restoring a hundred times and restarting from the beginning several times, don't play this game!
