You don't have to complete a scene before moving on to another one. If you can't find all the items in a scene click on the 'Map' icon in the bottom left of the scene. Click and go to another scene. You can always come back later with a fresh look at the scene you couldn't finish. Clicking around an area in a scene can be rewarding sometimes. You might click on some obscure or ambiguous items. Don't click fast. If you keep your clicking to a slow pace you shouldn't get in any trouble. Some of the mini-games can be very tough. Take your time and look at the picture provided of what you are supposed to look at and try placing the big items first. While moving around the puzzle, flipping and item will automatically drop it when the placement is right for it.
