A neat little idea, but I think using sound as a game mechanic is really hard to do in 2D and I feel like you ended up with a pretty good result. I would have loved some music though. A neat jam entry though!

Cool concept, though I'm unsure how it relates to the theme.  I really like the enemy design and how they can extinguish torches.  It was rather difficult to see the walls though as they are nearly the same color as the ground.
