Compared to previous episodes, it tries to bring some diversity in the places visited by spreading a little more than half of small puzzles in separate stories, taking place around the world.
If the frame is growing in diversity, it unfortunately tends to distract the player from the main story. True, it takes a final reserve and major revelations, but between the beginning and the end, the narrative does not move much.
The other consideration for this construction "mini-episodes" separate is some standardization difficult puzzles. Certainly there has some puzzles a little racy, but in general, the challenge is less important than the first few episodes.
This is not necessarily a surprise since it is a dynamic that I have found in recent years on the series "Professor Layton".
However, and this is a good point to make, I found the puzzles were a bit more varied than usual.
In short, in the end, I had a great time at "The Legacy of aslantes" and I hope that the series will return soon in one form or another, provided of course .... it retains the main characters to which we are attached. ;-)
