HowToPlay? (9k) vs Wurfmaul (1k)

Hi i’m hoping for a review of this game, it started out well for me he had a weak group and i chased it.

Unfortunately it ended up living at move 78 (o3), the main mistake on this game I guess is when he pushed at n2 instead of a hane i should of made a bamboo joint with p3.

Thank you in advance for your review.
