This was thrilling! The complete darkness mechanic was an interesting way to make traversing a smaller dungeon more complex. I wish the touch command marked all the cells adjacent to you, not the one in front, as I couldn't find a good use for it as it was.
It took me a couple tries to figure out the battle system, which is a bit ironic because it seemed like we both had similar mechanics with attack, defense, and delay. Once I actually paid attention to the UI, the combat was tough, but manageable.
Good job!
