To me, Emerald City Confidential is much more adventure than casual.

It seems that Echoes of Sorrow was developed by Blitpop Games. The game on Tim's list that I know of that was developed by Dave Gilbert of Wadjet Eye is Emerald City Confidential.

Ob, I agree that Emerald City is adventure lite, maybe not even lite; but being as it was produced by Playfirst, the developer of Diner Dash and other hugely successful casual games, it ended up being sold/directed at the casual games market. Unfortunately all of Playfirst's casual games were removed from the Big Fish website many years ago, but fortunately I have many of them.

I don't know where I got the idea the Echoes of Sorrow was related to Wadjet. First Wadjet was created in 2006 and Echoes didn't come out until 2011. It's developer is no longer with us, even though the publisher, Alawar Games is still alive and kicking. Got my wires crossed somehow. Which unfortunately happens with increasing frequency as I tack on the years.
