Jump to the left or right onto the first bounce block, then to the second. From there, jump onto the ramp, hold the arrow key facing towards the top of the ramp and jump until you reach the top. Then open the door, and slide down the other side of the ramp. You should land on the bounce block if you hold nothing, and from there you can jump right to the exit.
