I like the 8-bit artstyle quite a bit! Pretty nice for something done in only 7 hours. I do agree with a few others that maybe adding a bit of audio and an implementation of the special object would be nice because I don't really have a basis for what to rate in those fields... For what little time you had this is still pretty good and I commend your efforts, nice work!
That is all, have a wonderful day! :D
