THINK I've gotten as far as I can, beaten the demon (twice), found the temple in the desert but can't really do anything, Liam just talks about how he's the chosen one. Only thing to do now is build up Nel and the slimegirl's relationships, see about getting those legendary treasures and wait for the next update!
One thing I I found both irritating was that when some critter was having fun with Celica Evie wouldn't do anything to attack the creature. This might make sense (she doesn't want to hurt Celica) but if there's just the one creature enjoying Celica Evie either heals for a really small amount or just sits there waiting for Celica to get whatever it is off her...
