Haven't done it and I won't. The main reason is that most of the very rare times that I do die are due to recklessly building in high places on an empty stomach. No point in subjecting myself to that disappointment.

If I didn't have that habit I think the only two things that could pose a threat to a first-try are either a pack of wolves or a stealthily migrating deathsquito. The vast majority of enemies are pants. They practically cheese themselves.
