The map itself is pretty linear (left to right), the only exception is the area after the first moving platform where you need to go down, there are two hot springs there. The way the game was when I submitted it I see no way to go back (and reach the hot springs you might have missed) once you've made it past the orb wall. I will keep that in mind for later. When you reach all of the hot springs (and activate them) you should get a very quickly scribbled "You win!" image appear over the screen.
