Im not sure how you completed the demo without using the keycard on the door next to her, which gives you the item used to feed her. Is there a bug, or did you not see the "to be continued" screen?
Im honestly not sure how to feel about the balancing of the chase scene. Only two people have reported difficulties with it. Perhaps the problem is that i need to introduce a brightness slider rather than change the chase sequence, or increase the field of view in that scene i guess.
