What do I do to get past level 66 of 100 Floors?

For level 66 of 100 Floors the developers hid the tool you first need within the intricate design of the floor.

If you look all the way to the right, almost half way back to the wall you can see a long stick. Tap it to add it to your inventory.

Now you can use the stick to get the grappling hook off of the wall.

With the grappling hook in your inventory, tap it to use it and then tap the large metal hoop on the door.

All that's left is to "yank on the rope" by swiping down on the hook to pull the door open, and you're on to the next level.

There are just four levels left so far in this iOS game, recently ported to Android, but the makers have promised iPhone, iPod, and iPad users, as well as their Android brothers "more levels coming soon." We can't wait!
