The music is okay for the first minute, but then the repetition gets annoying. There are too many lives, and the menu itself is overly simplistic. The gameplay does exactly what it should do, but the idea before that isn't brilliant.
Too improve, I suggest using a far smoother sound, as the synth of the current music can get very annoying. Also, I don't think you should be able to highlight the text, as that seems to detract from the presentation. Also, if in the tutorial you had a graphical representation of what the gameplay should look like, it would go a long way in helping. If you fail one level you should not be allowed to continue to the next, and finally, the actual movement of the bars would be made significantly better if you moved the bottom bar with the left and right keys, and the right with the up and down keys. A nice addition would be bars at the top and left, each about half the size of the screen for a more hectic pace.
