The part I had the hardest time with was the storage closet and getting everything together before I ran out of air. I didn't realize you could change the view so that you could see the plug under the desk to select it and add the magnesium powder. I knew that's what I had to do but didn't know how to get to the plug, so I died about 4 times before I figured it out. I saw some pics and a video I think for 2. I can't wait.
