There are strict privacy rules that prohibit universities from disclosing student information. If you have the student's name from the article, you can probably do a Google search to see if you can find the student. However, I see that you said that you have already applied for the registration so you may want to wait and see if anything happens during the opposition period. Something you may want to think about is whether your name could be descriptive if someone else creating a similar game called it the same thing. That's something that the examiner will look at.
Contact the blog owner and inquire if they can put you in contact with the student. Note however that an intent to use is not the same as actual, continuous use in commerce. In the United States, the general rule is that trademark rights are based on priority of use in an actual business or trade. Consult with an attorney to determine the extent of the student's right to the mark, if any.
