A few problems.
The music stops pretty soon after the game begins. There is only one type of enemy. There is only one type of tower. The level is short. Other than that, it is what it claims to be. It seems like you didn't spend a lot of time on it. I suggest working on it heavily and then resubmitting it, as it is likely to be blammed as it is. Good luck with your future games.

i can't give you a decent score. it's pretty much a carbon copy of a tutorial, and you didn't give credit to the tutorial either. the purpose of tutorials is so that you can learn the basis behind a game style. I would suggest that you find your way back to the tutorial read through and try to think about what you could change to make or more original. Also, if you are going to use code from a tutorial this heavily you should definitely give a thank if not a link to the site. I hope to see you creating original games real soon.
