Interesting game, I found the controls and concept relatively easy to understand - however I just couldn't light the third candle for some reason. I couldn't tell if it was bugged, or if I was out of flame and the game wasn't telling me properly? After 5 or 6 tries I gave up. I did generally understand the game (I think) and liked the spooky atmosphere.
Your game is included in this playtest, I timestamped the chapters to make it easier to find
