Thanks for feedback. I just have fixed jumping – now you can’t jump so high, but you should see platform on which you want to jump. I also added animation of taking hit according to your advice, and put on map several bottles with life potion more.

Added alternative controls if you hate standard:
space – use item
right alt – jump
right shift – change item
