The 23-year-old is interesting a number of clubs, including Hibernian, after netting 47 goals in two seasons.
The Irishman, whose contract is set to expire, told BBC Scotland: "I'm going to have a good think about it and hopefully decide in the next couple of days."
He added: "I'm hoping to speak to the gaffer. I've really enjoyed my time here so far.
"Obviously I have to sit down and see what my options are but I've really enjoyed my three years here. I can't say a bad word about the place."
