Analyze please
I think 12 h3 was a weak move, f4 might have been stronger or h4. The idea with that opening is to ATTACK on the king side. It's called the 150 BLITZ which means pawn blitz and hard.
White followed up on 13 but maybe with 12 f4 then 13 Bd4 might have worked...
..Nxd5 was actually quite strong because it opened up that c file which is where the downfall of the game happened.
19 Kd1 I think 19 Kb1 would be better...
The Scicilian is all about knocking the whole game off-balance. White positionally seemed to not leverage that early on and black did.
The opening actually left some advantage for white early on and the pawn structure mistakes really showed up later.
Also, I don't have time to analyze this much deeper than that but I'm sure that if the queen trade hadn't happened, there would have been stronger tactical opportunites for white.
Please annotate the game more deeply. A few ?! and ? is not sufficient enough to understand the intent of the moves being made.
