I think it's a perspective trick. It looks like there's steps right below where Mega-ED & Mini-Alice are standing. I also think there's some dream weirdness happening. I always did like astral adventures, the dev/writer can throw some bizarre shit and you just roll with it because reality bends to one's will there. (Cool thought: Lucid Dreaming skill a la Lovecraft...)Hay hay hay! I havnt got a mum fetish. BUT the point still stands. Pregnancy game + Fertility goddess = Wanna Fuck!
About the potential Nergal, it still dosent explain why MC is so small... Although I MC is shrunk I feel it would be a missed oppertunity not to have the Rats attack MC as enemies. After all the time MC has cought & killed em in the past, Via La Ratolution!
