A little simple, but pretty good for someone who's just learning! In the future, try mixing things up more-- like new types of enemies, or making the game look different over time, so the player is always discovering new stuff. Also, I didn't know there was an attack until I saw the other comments; the first time I played, I just ran past all the skeletons since I didn't realize I had a sword. Always make sure to tell the player what tools they've got in their arsenal!
