Of course!
If I may make a suggestion... maybe when the monsters are too far away to see or hear, you could move them instantaneously, and the closer they get, the longer it could take for them to move. This would make it so you could move a little more freely around the map when they aren't around, and increase the suspense when they get closer to you. (EDIT: or possibly add a second distinct moving sound clearly different from the character's footsteps to let you know the monsters are moving, which could get louder or softer with distance to provide another form of feedback for the player... regardless, even knowing it was turn/tile based, which I figured out pretty quickly, it still makes the game uncomfortably slow... especially when turning).
