Tip 1: Pause the Game
When you pause the game, the timer pauses, too. Since the pause menu only covers a bit of the screen in the middle, you can still look for the things you need to find while the game is paused.

Tip 2: Click during Pause
While the game is paused, you can still click on objects to find them.

Good luck, have fun!
I hope these tricks will be of help.
