Wow! Amazing feedback! Thank you so much for your kind words! : D it makes me really happy that you enjoyed it! I had a lot of fun creating the landscapes and the bizarre characters.
Regarding the //spoilers//
Actually, the guilt induced nightmare is only a theory of Doctor Weir. If you noticed, Malva's mother was behind her father while he was talking to the doctor, and she had been dead for some time (and she looked like a monster). And Erika can communicate through e-mail even though she is dead. So I wouldn't say it's all a nightmare or dream. There's a chance that what you see in that ending isnt' even real life at all!
