Be aware that the game continues even if you forget some objects, as long as you did not need them to open doors or secret passages on the previous level. You will pass to another character and probably need the forgotten object later in the game. If you end up at a dead end because of this, you will have to start the game again. To help avoid this, make sure the rumble feature in the controller is enabled and pay attention to it. It hints at things that you might not see. Keep your eyes open and read everything where you find yellow words. They are probably a hint as to what needs to be done.
