This is basically a hidden object game, albeit with a very good storyline to follow as you move from challenge to challenge looking for objects.
We've put together a few general tips that hopefully will help you find things more quickly and waste less energy.
1. Not everything is visible
When you get a hidden object picture you have to find a number of objects, but not all of them are directly visible, some could be under other objects, inside drawers etc...
2. Interact with Objects
In one level in particular there is a mirror that you can tap to turn to change the reflection it gives in order to find an object. Look for objects that you can interact with. In another example there is a torch, it can be turned on to shine light onto an object in order to see it.
Also, other objects can be opened (boxes, drawers etc...) to reveal certain items.
3. There is always a solution
Have a look at what can help you to find the objects you are looking for. For example if there is a stuck drawer, you may need a key to open it... Or even oil to loosen it!
4. Use a Hint
If you are still stuck, use a hint, sure you'll lose more energy, but it is the quick way to find a solution if you are completely stuck!
