This is level 2 of the A-Tunnel.
This level is really easy for a later level. The Runner is best as the platforms require average jump height and distance. The Lizard would work too. And the Student as well. So really, this level is easy and you should be able to pass it without much trouble.
As for the Lizard, looking when and where you jump since if you jump too late, you may end up jumping too far away and overshoot the platform, failing to beat this level.
If you use the Student, just be careful that you don't float too high and accidentally flip onto the ceiling. Avoid this happening unless you planned to do so.
Once you pass this level, a cutscene will be shown. It plays when you click the teapot on the map. More information can be seen in this page.
The Pastafarian has drawn a teapot on the Runner's map, annoying her slightly. The Runner demands to see where the teapot is. The Pastafarian says the Flying Spaghetti Monster put it there. She then says that it is too small to be seen. The Runner asks about how the Pastafarian even knows about it if it is too small to be seen. The Pastafarian says that the FSM puts a teapot in every solar system.
More can be found on the Story page.
Later, in Bridge building, the Runner mentions the teapot again.
