couple things, first of all, love the game! truly great stuff here. that being said, having played both the demo and the current paid ver (0.2.5d at time of writing) i have encountered the same bug twice. on the night where you are you are supposed to find annie holding the knife near the start of the game, the scene fails to trigger (ie annie is there but if you walk up to her nothing happens) if you advance time from going inside from the back yard. i could only get it to work by snoozing through the day.
edit: additionally, later on in the game the dialogue reverts to calling the player Lewis instead of the entered player name
