A Bridge to Daylight

Immediately grab the topaz directly to the right of your character,

and another topaz to the far right to the upper right of the screen.

go down the path and pull the switch. This will stop the constant arrow barrage. Go to the end and pull the next switch to pull the yellow switch back. Go down and aim to get the timer to stop when you are in front of the closest yellow push block. The one on the end of the path will push you into a trap. When the yellow push block has pushed you down, go to the next area.

Before doing anything else, grab the Necklace of Dreams fragment in the bottom of the screen. It is between the spear and a snake. Grab the spear and go pull the switch. Go back up and push the pillar that is on the gray platform. Go towards the arrow wall and pull the pillar to have it align with the previous pillar you pushed off of the gray pressure plate. Now push that pillar back onto the plate. Throw the spear at the snake behind you and go run and complete the game.
