About this game

In the game, players must carefully move the screws and nails to complete each level. You have a time limit. You must remove all the nails holding down the metal plates within this time. The plates must then fall completely to pass the level. As levels progress, the game gets harder. You have to watch the relationship between nails and metal plates carefully to work out the right way to take them out. If you get stuck, you can use the tools the game gives you to help you.
