It's a school assignment, and in big, underlined, all capital letters, it says, "THIS IS AN INDIVIDUAL PROJECT. NO OUTSIDE HELP IS PERMITTED!"
I also went up to the professor and asked if playtesters were fine, since it IS a game development class, and testing a game IS part of the game development process, and he said nope
So... nope.
Although once the game is COMPLETED, the assignment can't dictate what I do with it afterwards. I wouldn't exactly turn away any feedback after the game was released, and it IS a sign of a good developer to improve his game based on user feedback...
EDIT:
Also, this support is awesome. I'm feeling more and more assured as time goes by!
