It's a minor suggestion, but maybe you could clear the screen when a level is completed? The key is sometimes visible in front of the text.
Otherwise, keep up the good work.
some bugs/annoying things:
when you restart a level the timer doens't reset;
sometimes the moving parts colide because of the delay caused by hitting the apple, blocking them;
the apple sometimes disappears
Nice game, but my score doesn't show up in the high scores. also, i've noticed the ball is just a slight moment incontrolable when you hit a score multiplier which in my case causes it to miss an arrow :(
