GameZebo: Like solving brain teasers? Have I got a game for you. Echoes of the Past: The Citadel of Time puts up a mess of seriously good puzzle action blended with a healthy shot of great hidden object searching in a game that's not perfect but that does what it does so well, you probably won't even notice.
JIG: Ding dong the witch is dead! Wait, what? She's still not dead? Not only that, the old hag is back and badder than ever creating havoc in the museum in Echoes of the Past: The Citadels of Time, the latest hidden object adventure hybrid by Orneon and sequel to both Echoes of the Past: Royal House of Stone and Echoes of the Past: The Castle of Shadows. Perhaps it's time to stop hanging out in that darn museum? Just saying.
