I really liked your level design. It's honestly one of the best in this jam so far. The core gameplay mechanics are also really well put together.
I think it could be even more interesting if the amount of candle wax you have left had a stronger effect on your character's light, since that would make it work better as a visual indicator of your health. That said, I can also see how making the light dimmer could have an impact on the game's difficulty because of how much it would affect the visibility of the environment. Which would likely cause a lot of trouble.
