I'm not much for hidden objects games. This is similar to a lot of the Big Fish games. I bought it hoping there would be some puzzles to work with, but there are very few puzzles, if they can be called that.
I finished the first of 5 treasures within an hour, so I imagine the whole game will only take a few hours. Some of the things that make the objects difficult are the scenes/colors of the object and knowing what their definition of the object is. The trailer shows two of the "puzzles," so if you do not want to get the answers spoiled, don't watch it!! Hopefully you read the comment before watching the video.
The voice acting could be much better. Unfortunately, there are weird pauses and it seems like the voice actors were just reading off the page and not so much acting.
If you like the hidden object genre and don't care too much for the puzzles, this is a pretty good buy currently at $1.25.
Note: I was playing on a touch screen, I didn't realize that if you hover the mouse around the scene, some objects will show a cog that you need to interact with and make this a lot easier.
