Immediately, when you enter, head left and shoot the eye on the wall. When the chest appears claim your Compass. Head straight south and stand directly under the Door. Use Din's Fire to melt the ice and hit the switch (it doesn't always hit the switch at the same time, in which case step back and shoot it with your Fairy Slingshot). Through that door shoot the eye in the pit to claim another Small Key, then back to the big room. Climb the stone wall and up the stairs (watch out for flying pots) to see the time block. Jump onto it, and pick up the box (if the box is on the ground, play the Song of Time so the time block appears directly over it, then leave through any door and immediately come back). Jump straight west to land on the second floor, then take the stairs to the top. Set it down and play the Song of Time to move the block, then jump across with the block, and down onto the statue's hand. Set the box on the button, then one last time climb to the top and through the newly opened door.
