I like the atmosphere and the idea of navigating a dungeon (and a surprisingly big one at that) lightning torches. I also quite like the decision of recovering the player health when lightning a torch. Makes you be extra tense if you are down to one heart and are looking for the relief of lightning the next torch. Controls feel clunky to me, it seems like my inputs for movement were not always being registered and I didn't quite get accostumed to the rhytm of attacking.
I'm also not sure about making it so you cannot change direction without movin a square. I see that it makes for some great navigational puzzles avoiding monsters and positioning yourself to attack, but in some rooms, but it feels, I suppose unnatural would be the word, to me, and in some rooms I found it frustrating because I would be thinking "if I could just turn aroudn this would be a lot easier". Still, great submission with a mix of fantasy and spooky, and a strong Game Boy feel.
