Not too bad for your first project, but still a bit rushed. It had laged a lot and it was hard to control the cube because of that. Also, what are you supposed to do when you get to choose the difficulty and the area? I do not have a play button or anything like that afterwards.
And also, I recommend puting the name of the song, in this case Stereo Madness by ForeverBound in the "Credits and Info" or your game might get taken down or something.
