Now put the crystals in the order that is shown in the normal dimension: Top - orange, Left - red, Bottom - purple and Right - green
You will find a empty book inside
Put the book in the bookshelf in the other room
The bookshelf will unblock the path to top and bottom floors.
But first let's deal with the ghost that is in the attic
Use the wood cross on the ghost to make her go away
Tap the small container on the table, and enter the patters that you've memorize earlier
You will find a orange spring wire
Now combine the wire with the clock
Go to the lower level
Use the sword to kill this guy
Take the stick
Place the stick on the stand
Now go to the top level
Take the lantern
Go down on the ladder
Place the lantern on the floor
Tap the mirror to go to the normal dimension
Take the sledgehammer and use it to break the wall
Place the clock on the dynamite and get out of the house in 20 seconds
CONGRATULATIONS you now have you're revenge.
