Thanks for input. Balancing difficulty is always tricky and I agree. I did made game a bit harder since it short but at start enemies were even bonier and harder to fight. Jumping is a good idea, mainly tried to mimic Quake player movement. Sounds is my weakest link, I had walking sounds but it was too distracting so had no time to tweak it. I really wish to make more if people like this game so your comment is very encouraging.
