Each move looks reasonable, which is exactly why the trap is so effective over the board — White walks into it while trying to play "normal" developing moves.
This pattern is well known from master and correspondence play (Traps - Chess Traps - Danish Gambit Queen Trap 1 - C22 - https://lichess.org/@/gambits2pieces). Recognising it early lets you either spring it as Black or sidestep it as White.
