Great job on the graphics and audio, to create this atmosphere. I was really into it, too bad it didn't go further.
The animations, mostly the running with your sister and pushing water onto the fire, were impressive.
One remark is that it's a bit too dark, at least on the characters' location. I played around myself with lights but never managed to find a way to fix that, so I wouldn't be able to help on that. But the characters we a bit difficult to see. Maybe a warm light on them, to show the fire reflecting on them or something?
Anyway, great work. I hope you'll continue!
