Very nice submission! Also a great implementation of the theme. The art is done very nicely and the puzzles are clever. I'm also quite impressed that you took the time to make the save load system work inside the browser! I found 1 bug related to that actually:
When you die, you keep your collectibles. I noticed that the candles I collected are still gone in the new run. So that means I have to play with only my initial 2 candles.
I also found that the dialogue goes by a bit quick, which caused me to miss some of the text
You mentioned that English is not your first language, so I compiled a few things that I found:
..[yeah] that's a way..
..You [could've] just summoned..
..start from the [basics]..
..somewhere [at] the entrance..
..how many secrets and [collectible] items have you found..
