I have almost rainbowed(compleated with all classes + badges) two vicious (the hardest dungeons on the game) and I still mess up the god-puzzles. So I'm not sure if that's a good way of messuring your skilllevel.
For goatperson, remember to save glyphs for when fighting the boss or some high level enemy. As you won't have popcorn due to his food, and level ups won't heal you anyways. So don't be shy on not leaving popcorn around.
(Just incase you don't know, Popcorn refers to lower level enemies that can easily be killed while killing higher level enemies for mid-fights level up (full hp and mana).)
Anyways, glad to see you enjoy the game!
