I don't mean to be rude to you since(in my opinion at least) you're a top level player who doesn't act like a total jerk, but there is a game analysis forum.
Analysis of my horrible, passive game :(

No - there are 960 different positions - basically, you shuffle the pieces on the back rank randomly such that the only restriction is that bishops must be on different color squares.

I love chess 960. I tried to analyze this game to give you an opinion but you are obviously a stronger player than me so I don't think I can offer much. Seems like your space advantage and full development along with his bad bishop and unconnected rooks could be capitalized upon. Your opponent played a lot of moves you had to immediately react to. If not for that I was thinking a queenside attack might've been a good plan.
Can people give advice on this game? It was played at the 3+2 time control, so fast, but not that fast. I felt like I was slowly crushed, and that my opponent could have beaten me much worse than in the game had he not been in time pressure.
I just didn't know what to do as the kingside attack gradually proceeded. What do you guys think my plan should have been? I've added some brief annotations on what I was thinking.
(And yes, this is chess960)
