Someone could make a review of my game ? I'm 10 Kyu

Do you have specific questions? Could you explain why you resigned instead of playing the ko at N5?

You were winning the game, but M19 should have been played at L18.

Well, I don’t know why I thought that even if I win the ko the group could live, I misread that, I would like some thoughts on the upper side in the begining, has a pattern in that situation ?

@mark5000 posted some excellent comments. Black’s bad move at O16 saved white.

Posting here because I forgot to post earlier.

Thanks, man
