I recently purchased Treasure Seekers: The Enchanted Canvases from Big Fish Games with one of my game club credits. I found it to be a very interesting game, not something you will get through very quickly.
In this game, you must help Nelly to find her brother, who has been imprisoned in a Romanian castle. There are different tasks that are required of you, and you must go through various steps to complete each task. Hidden objects also come into play, as well as mini games sprinkled throughout the actual game itself. The game is also comprised of enchanted canvases which you actually enter, and you are instructed throughout the game what is required of you.
Treasure Seekers takes time, thought and patience to get through. I'm nowhere near finishing this game yet, and there is even a strategy guide available to help you along the way. I love the graphics, everything in this game is very realistic.
If you are interested in a computer game which requires some thought and effort, you would enjoy Treasure Seekers: The Enchanted Canvases. Try the one hour free demo on Big Fish Games' website and experience for yourself what this game is all about.
