Interesting storyline, an auspicious opening demo that leaves the player on quite the cliff-hanger. Hopefully in the main game we'll see all the NOC characters reveal more about their stories, and we'll be able to see if Mamma did some bad things to people down in the basement...
Only criticisms I have thus far:
1) The fruit in the walk-in fridge area should be displayed bigger to the player - whether this is through icons or bigger text
2) The main character doesn't really seem to show any emotion or interest when the 'creature' pops up. This either means she can't see it or it doesn't pose a problem to her. Would like to get some acknowledgment either way!
Apart from that, great demo!
