I want to give this game 5 stars, intellectually. It had the good HINTs/STRATEGY GUIDE (bundled). It had a MAP feature to speed travel and show you were the next actionable locations were. It had the JOURNAL system that auto recorded all the clues you had seen elsewhere in the game. It had BONUS CONTENT (i.e. "Secret Room", Wallpapers, Audio Tracks) which unlocked when you found enough of the secret mysterious symbols throughout the game. It had a reasonable plot (for a Hidden Objs genre game), good atmosphere/feel, and the Hidden Objects puzzles threw a few Aha moments at me.
However, it felt like just before it hit excellence in most of those areas, it would fall slightly short, again and again. It had a LOT of sliding piece puzzles, which I find personally annoying. The plot didn't go far enough for me to get personally invested in it. The arcade puzzles were interesting, but sloppily implimented ... so I'd have to replay because it was sometimes scoring hits as misses (shooting gallery), etc. Overall it felt like things were being added from a master "to do list" of what games should have, instead of being organically grown out of the game itself.
* Achievements in Game (But no Steam Achievements)
* I wish it had Steam collectible Cards, too.
* Soundtracks in Extra Content section: Only 1 of the tracks would play music (with LONG delay)
Overall Rating: 4/5 Stars (even with all the bonus features)
