since this is your first game (and for the fact that that is still more than I have made...) it is pretty good... I agree with kingguthixx... expand on this and get better! 3/5
Not bad... I liked this game. 4/5 because it needs a little work with physics and some more diversity in gameplay would be nice... keep that in mind for Null G 2. :)
I liked it... I think it is a true work of minimalistic art with wonderful storytelling... I got more out of 5 notes than half of a movie could explain. 5/5
