This is Level 11 of Run 1.
There are a lot of holes in this level that can make this level difficult. Although pretty much any route works, for beginners, it is recommended to switch your gravity so you are upside-down relative to your starting position. Then from that point on, it becomes basic maneuvering and jumping, probably making it the easiest route of many available routes. However, as mentioned, any route will work, so you don't really have to follow much advice for this level. Just dodge the gaps or jump over them if you cannot avoid them and the level should be relatively easy to complete, and you will move onto the next level.
