Blam! Games is one of the developers that we rarely see in the Big Fish portfolio. The only other games I've played by them are Dangerous Game: Illusionist and Fierce Tales: Feline Sight. I had rated these games 4 and 3, respectively, and I didn't view them as replayable. Thus, I didn't have high expectations for this one.
The trial was short, but long enough for me to decide to buy the game. I was pleased by the diverse HOPs and the puzzles-within-puzzles.
What really sold me, though, was the storyline and the ongoing interaction with Greek gods, demigods and villains. The developer clearly spent some time researching mythology so that the characterization of the gods and myths was spot on.
I also enjoyed the gimmick of the Amulet of Time, which enables you to travel between now and then. Of course, we have that in other games: it's usually referred to as a teleporting map. ;-)
This won't be the best game you've ever played, but I think most people will be entertained.
