I am currently trying to find all the secrets in Jasper's Journeys. First, a big thanks to the level guides here in the bbs. Unfortunately, they only reach to level 9. Now I am stuck in level 13 where I do not know how to get to the left part of the surface. Buying the flying potion from the inn and using it back at the start doesn't take Jasper high enough. I figured that a jumping potion may give the needed height, but couldn't find one.
Is there any other way?
