Nice story & I like the how the game tells story within mini games.
The cutscenes animation are pretty good and high quality.
Some of the hidden object games took me plenty of long time to find the objects, they are nicely hidden (but kinda frustrating), but all of the mini games are pretty simple.
Also there is a nice guide for collectibles so that I don't miss any of them while playing.

Needs at least 2 play through to complete the achievements (1 with full hidden object scenes, and 1 with full pair of matching games).
The game is IMO lacks of instruction of what is needed and how to do something, especially towards the end of the game.

After playing some times, the game's loading time of cutscene and mini games becomes very long (both before and after).
It takes more than 5 seconds and sometimes even not responding while loading.
Also the game will not responding for a few seconds after back from alt+tab-ing (both in fullscreen and window mode).
Restarting the game seems to fix this, maybe there is a memory leak.
The bonus game also has issue with very laggy fps and broken hint which keeps pointing to broken bowl.

Despite that, I still recommend this game to those who already played the Enigmatis 1 & 2 just for the completion of the story. But I don't recommend if you are just looking for a fun gameplay experience.
