Customer Reviews

Okay - versions 2 & 3 are better

I had version 2 first, then 3, then decided to go back and try this one. What can I say? The game has evolved and this version is the primordial ooze.

The basics of game play are here, and I've only found one bug - a hidden objects level where almost every item was at the edge of the screen and some could not be grabbed even with repeated touches.

My biggest complaint is the absence of a relaxed mode. This is a casual game and I often play it in circumstances where real life is more interesting. Become distracted a couple of times on this one and it's game over.

Best advice: start with HWOTD 2. You can try then buy. The game play and graphics are much better - perhaps not surprising as BFG no doubt provided some additional funds.

Good game, but some glitches need addressed

The glitches I've found are on 15.5 & 16.5 where it shows the extra time button as charged & available, yet it will not give you the additional time you've earned.

Otherwise it's challenging, yet not to easy. I can't put it down : )

Hidden Wonders of the Depths 1

This is a great game. The only problem I ever have is sometimes the buttons don't respond all the time in the matching games.
I have the full version.
