I tried a couple new games, with a default female character morphing into a hellgate demon right away, heading in to talk to Morgana and then morphing into Gryphon, and a default male character doing the demons in reverse. I noticed just left clicking was enough to make the heads appear, if that was an issue with the morph.
The doors in Farglow can not be opened; they were placed there to make a more realistic village, but there is no extra content associated. Originally just having a message that they couldn't be opened through lockpicking was good enough, but the Developer Mode can reveal that design shortcut. If you 'goto Region' 004_Tutorial Main and look around (perhaps morph into something that can fly) you'll see similar examples in the design of the environment.
