There's a bug where when I walk down/up the stairs to get to/out of the library-type area, it stops for a second then jumps into/out of the room suddenly. The matches are almost impossible to see. I picked one up accidentally thinking it was a sliver of pixels showing up from a glitched-out envelope, then I immediately wondered if I had missed any before. I went to go explore the house and see if I had to turn off any lights without following any of the instructions (door-knocking, name-writing, opening the door, blowing out the candle) and it immediately jumped me into the game. That was a little confusing too. I feel like it would be nice if I could explore at least some of the house with the lights on first for contrast to the scary atmosphere.
Other than that, what I played was fun :) The match-running-out mechanic was cool and creative.
