even we lose in material. never give up until the game is over

In this game, my opponent choose white. I don't really know about the opening. I just know a little bit of them. sometimes I play the different opening and i know it but i forget what's the name.

I tried to play positional and always placed my pieces where it can control the center ( this way always work when your opponent play different opening or opening that u never seen before ).

My opponent play the opening that he tried to win tempo and insiative. When the game just played only 6 moves i got my position deep into a nightmare. I just can think maybe i lose this game but i try to keep calm and try to calculate constantly  ( i see one of my chess guide said that never give up even if u lose material becos maybe u still can win with your position and other factors ).

This is the game. i played black ( check it out )
