Good game with a high extent.

The Mask of Miracle is my second Layton game in the series. I only know part 1 on the DS, but you do not have all the games played by the story in the new game to understand the game is rather self-contained and indeed part of a "new" trilogy to the professor who even now its on the 3DS Start taking.
I would just note form my impressions:

Positive

+ New, beautiful 3d graphics with the same charm of the old parts to detail, like from the beginning.
+ Great cutscenes with reasonable 3D effect (only in the cutscenes)
+ A few, but beautiful songs
+ Exciting story with lots of twists and surprises
+ Time travel into the past of the characters
+ Many puzzles
+ Downloadable puzzles free long for 1 year, so 365 puzzles, this I managed to test so far are still quite simple, I'm curious what you will do here. But think the best puzzles will be there already in the game itself.
+ Some minigames, generally there are to solve puzzles or to do something;)

Negative

- 3D effect is very strong in the depth of the effect itself is actually good but myself pain the eyes of them because this game too quiet for this is because you do but also a longer period may be imposed on a puzzle, since switched to the effect you up.
- Some puzzles are repeated, only to something "other" way
- Difficulty of the puzzles vary greatly in my opinion
- Too heavy for children

For avid gamers riddle I can only recommend it, it can be played for a long time because you will get caught in some puzzles. If necessary, I recommend YouTube for solutions of puzzles, if you despite numerous tips should not come on it once.
