What do you think about this game?

Is it a gambit?
Bad play by white imo and later by black,
talking about the first 15 moves later It starts being cool.

Very nice finish and tactics in the second part of the game.
Mainly I give two question marks to the e4 square ??
Move 5.

Bishopxf3 as well.
It is an interesting game since it has plenty of ideas like stopping castling with the dark diagonal (a3-f8) .
Thank you for sharing.
