Overall it works well, it's just a little slow for my taste especially when climbing stairs one step at a time. Agree with HerbieG about arrows, and would add W or UP = jump. Two minor bugs I noticed: if you're eating a corpse and get hit by a turd then the turd flies through you but then you actually take damage after it's passed when you finish eating, and if you're standing directly on top of a bear and hit him then he bleeds and makes sound like he got hit but doesn't actually die.
