Let's look at the diagram.
1)If we count the material we notice that White has 3 minor pieces (Bishops, Knights), while Black has 4. So we can say that Black has the material advantage.
2)However if we compare the quality of the pieces we notice that most of the White pieces are outside of their pawn chains attacking targets inside opponent's territory. Most of Black pieces are still asleep in their initial positions. This means that White has advantage in development. In addition to this if we look at White's center pawns we can talk about control of the center and spatial advantage.  
3)Lastly we can compare the Kings. While White is about to castle Black King is temporarily stuck in the center where it gets attacked.

Based on the above information here are the ideas that should be considered by both sides:

White: Attack on the un-castled King. Develop more pieces and use center pawns to prevent development of opponent's pieces.

Black: Develop pieces as soon as possible. Bring their King to safety. Any trade of active White pieces will bring them closer to a position where their extra piece will be the decisive factor.

In the game White finds a tactic that allows them to retrieve material

11.Bb5 (attraction (inviting opponent to an unfavorable square) 11...Qxb5 12.Nxc7+(double attack) winning the Queen) Qg6 12.Nxc7+(double attack) Kd8 13.Nxa8

Later Black managed to hide their King and develop pieces. The final result could have been 0-1. The rest of the game is given without comments..
