I really like the concept of this. It takes me back to the 80's and games like Skull. Of course, it needs some refining, but I think if you stick with it and keep improving it good be great.

Personally, I don't think you need the turn buttons. If you just had left/right to turn and up to go forward, that would work and then you could easily implement keyboard controls.

Needs a map. I had no idea where I was going. Maybe something you uncover as you go. Found some stairs but couldn't go down. Perhaps having different things to help you see if you've been somewhere before, like torches on walls, spider webs and other decoration.

Fighting also seemed to lack any strategy. Just kept hitting swing until I turned them into a pile of bones.
