You got a start, you got a more than one map, you got an ending, combat works (even if it is a bit wonky with enemy collisions), there is sound, nice textures and models (I really liked the sword). So everything is a bit basic at the moment, but your setting is unique and I think you can go on to something greater now. Just make the traversable spaces smaller and movement a bit snappier, as movement is absolutely key in this type of games.
