Took days to get this one. I'm still not super happy as I made a major mistake with the wall jump tech and got stuck in my inventory and didn't know what to do. TehArck's route was so optimized that I had to look around for different tech to save some time. If you jump against a wall and hit jump and inventory at the same time over and over you can wall jump without using the Giraffe. Credit to Hfkool for finding that!
