A 4th episode always friendly

Thus we find what made the success of the series, ie:
- An endearing cast of characters, baroque, giving a fairly special touch to this series;
- A neat interface and accessible to all;
- An impeccable and timeless graphic design;
- And especially puzzles still interesting, appealing both to the observation that logic.

However the story is perhaps not as involved as that of previous episodes (especially compared to Destin lost).
It must be said that the investigation evolves relatively slowly and the suspense is not always well led.
Thus, some mysteries are resolved a bit too early (the raven) or too quickly at the end (the spectrum).
However, we like to attend the first meeting of the teacher and the young Luke, since this episode is before those published previously.

Regarding the puzzles, I found that there was a good balance between "guessing" and "puzzles", with perhaps a bit more variety.
The difficulty varies and well proportioned, with small puzzles easy enough at the beginning and more full-bodied puzzles as you go.

The help system is pretty much done, as the indices allow either to illuminate the issue from a new angle, or to unblock the impasse.
Remember that this is an option and everyone is free to use - or not.

The mini-games are a nice bonus, even if they can recall other minigames previously proposed.

Note also the abolition in the European version of a bonus game "London Life" kind of small very nice RPG that embellished the US and JP versions.
Certainly the European location was neat and we are entitled to a quality dubbing (in several languages!).
If the storage space of a DS cartridge is actually limited, nothing prevented the publisher to offer this mini-game on a second cartridge ...

Nevertheless, the spectrum of Appeal is clearly one of the latest "hits" of the Nintendo DS and its qualities are enough to captivate a large audience, both among fans and among the uninitiated.
