Heh, felt like a dozen times I wanted white to play Nc3 or 0-0. I guess he wanted to blow you away with aggressive moves.
On d5 I thought he had you :) 12.Qa4 seems hard to meet though.
14.dxc6 was a blunder, black has tons of initiative now.
Wouldn't expect you to see 18...Rd6 works tactically, well done ;)
