Oh, cool! My playtime is at 66 hours; probably 55 or so legit hours, the rest afk as is the case with John. I played a bit more tonight and beat Great Shinobi Owl (that was the boss I ended up getting). I made it to the final area of the game (as denoted by an achievement I acquired for visiting all areas) and then I faced Corrupted Monk. After a few tries I had this odd behavior where the boss allowed me to deathblow him in the middle of his shadow phase, otherwise I may not have won the fight. I got another vitality upgrade putting me at 17, with 10 attack power now.
That boss was a girl? :O
