What an ambitious first game! O.O
I am amazed that you manage to do that well in such a tiny amount of time... Well done! As some people already mentioned, reliable pattern recognition, with projection of 3D lines in 2D, is not the easiest thing to code.
However, like the others, I struggled with the controls and felt that the tutorial could be enhanced. I also noticed that the music is not looping.
I didn't reach the end and kept destroying meteors forever... Is there one at some point?
Anyway, nice job! :)
