I started chapter one and it pretty easy until finding the blue box. I was at it for 20 mins then I took a shesh then figure it out. So go they the vent , jump down, you should see a barrel, use your blue hand to stick to it and then wrap around the electric pole make sure you’re facing the hallway then use your read him to stick to the barrel, you should be holding the barrel at this point, move it to the red Square that has a paint brush and it should the gray tin wall. YOUR WELCOME :)
