The 23-year-old Austrian, who signed a one-year deal following a summer trial, helped the Tigers extend their unbeaten run to six matches.
Pusic, anxious to retain his place when Hull face Brighton after the international break, told the club's official website: "I did my best.
"I want to play and this is the reason why I'm here, because I want to make the next step."
He added: "The KC Stadium is a wonderful place to play football. The supporters were wonderful and it was a wonderful day.
"Getting three points was great and we're going to move further and further forward as a club."
