1. The Bounce Web clips through the wall in two orientations, you want to use the one that doesn't stick through as much. (The wall isn't necessary, it just makes it easier to hit the fist web properly.)
2. Hold the grid-align button to make sure the Bounce Web snaps to the proper place. (CTRL on PC, unsure on XBOX)
3. Walk into the first Bounce Web, and don't touch any controls after that, or you will fly off.
