This is a pretty good game, though it's a bit cliche... I like the idea of the three worlds, but you could go more in depth about the main character (Ariem's) goals, and how she could go about doing so. So far, all I've heard is that she wants to run away to make the Dreamworld perpetual, because she likes it. Maybe you could explain more about why she likes it, what she thinks of the evil people, etc.
Also, your faceset's are kind of weird. Even at the start, I saw that you combined Ariem's faceset with her mum's, which I find as kind of weird, seeing as they're drawn in two different styles.
And I think you should work on some grammatical errors, though that's probably not very high on your priorites. For example, when I saw the sentence "Some celery and a knife sit on a table" with no full-stop, it just didn't feel right. Maybe that's just me and my grammar Nazi ways...
EDIT: Found something else. When you go to the drawers next to Ariem's bed, it says "Just a few clothes." The correct way to word this would be "Just a few pieces of clothing."
Your mapping... Has some special bits, but for the most part is pretty plain. At the start,when I saw the water in Ariem's bedroom, I was like, wtf? Then I realised it was a bath, but it still looks weird.
By the way, this is kinda off topic, but I love your Australian English (mum, colour, etc). I'm an Australian too! (Or used to be, before I moved to America -.-)
EDIT 2: On huge maps, it's REALLY, REALLY LAGGY.
