On his 10 league appearance of the campaign, the Ghanaian emerged hero for The Frogs with a second half equaliser which forced a 2-2 draw away at Huesca on Saturday.
He netted just four minutes after coming on as a substitute.
"I'm very happy. It has always been my prayers to score," Boateng said in a Levante video on Wednesday.
"I scored my first goal last weekend and I'm very excited.
"I think we're going to do a lot this year."
After putting the ball at the back of the net, Boateng received a momentary scare when the goal was ruled out for offside. Video review, however, reinstated the strike.
"The moment of the goal was a bit crazy because after scoring they all thought it was cancelled," narrated the 22-year-old.
"The referee validated it and I was very happy."
The striker also spoke about his side, who impressively sit ninth on the league table.
"I think we're very good and compact," said, the Accra-born.
"We had some difficulties but now we're playing and doing well."
Boateng, who joined Levante from Portuguese club Moreirense in 2017, registered six La Liga goals last season.
