This level consists of two almost entirely separate paths, one leading upward and the other downward. After you've played the level, please post here saying which path you wound up on first.
Also, if you encounter anything wrong with the level that I or my beta testers failed to find, please let me know, and I will upload a corrected version.
One more thing:
There is a secret challenge and reward in this level. It is much harder than the rest of the level, and is excluded from the general difficulty rating.
