After getting the second puzzle piece behind the grate and passing the second grate to the tree with drawers, I can't climb the bottom drawer. When I pull it out, it flies all the way out, closes and then opens very little. Not sure if this is a bug or I am doing something wrong. Please help. Thanks.

This issue has been resolved. It seems I needed to flatten my nose against the drawer to climb onto it (meaning I was too far away). :(
