Nicely done and with catchy music.
There are (at least) 2 bugs though.
The Mangenta gets cut-off at the right side:
And you're playing the sound whenever the mouse is pressed, which means that it restarts the sound effect every frame and it doesn't matter where you click. You should play it only once per click (where a click is defined as when the mouse button gets pressed down and comes up again) and only over menu entries and memory cards or at least only within the window.
