This is Level 33 in Run 1.
This level is really just a blank tunnel with a lot of large gaps and holes here and there. This tunnel has snake-like features (since all of the tiles in this level are interconnected), making some parts of this level an easy maneuvering challenge. In fact, there are enough tiles in this level that are connected that you can beat this level without jumping. However, this level is exponentially easier if you use the jump button because it requires less maneuvering skills.
Overall, just avoid all the large gaps and holes to survive. There are plenty of tiles around you to choose to land on. Focus on the larger platforms because in cases where you are jumping, it would be easier to land on one of those rather than one that is one tile long.
