I absolutely love this.
The various sacrifices are really well designed, with some genuinely difficult decisions to make.
Gameplay is in general really well thought through, in particular the imps - the telegraphed moves and the fact that they can move candles forces planning ahead, especially as they get faster.
Music is superb, and really sets the tone for the game. It's ominous and adds to the dread, but really encourages careful and considered play rather than rushing.
I always love seeing what people can do with really low res pixel art, and thought this was wonderful. The sprites are amazing!
The title font is great (falling in love with fonts is a running theme for me this jam, apparently) - is it custom made?
My final score was 14.5
