This game hasn't shown up in my queue yet, but after the thoughtful and detailed feedback you left on my game, i simply had to come play it!
This game is by far the most polished game I have played so far!
if I had one note I would say that the flame didn't visually go out on the character sprite when the light dimmed, so it wasn't immediately obvious as to why i couldn't light the candle once that happened.
Another thing, maybe some candles could be pre lit to serve as checkpoints? this would allow for some extended darker platforming challenges where you have to dodge enemies while platforming.
This game has potential and I could very easily see this mechanic being added very satisfyingly to a Metroidvania.
I look forward to this game showing up in my queue so I can properly rate it.
