Awwww yeah, nice one! You're super good at these mind-bending puzzle mechanics!! I love that feeling you get when you illuminate an invisible wall or realize you can't progress without a light you left behind. It forces your brain to adapt in a really unique way!
The art and atmosphere were intriguingly mysterious. I can totally see this as the base for a bigger catacomb-navigating adventure, if you decide to expand on it! Really solid work!!
