Nice start, but needs improvement.
I'll get this out up front, I have played far worse versions of this game. It doesn't glitch, and in general it works well. However just because I've played worse does not mean you'll get off easy, there are some problems. First off games like this should not be controlled with the mouse, it's just far to easy, a simple arrow key or "a d" set up would work better, this way you could set the maximum speed at which the player can more. Besides improving effecting the gameplay, a arrow key set up would allow for an animated sprite instead of just a static picture of AJ. You should have also tweaked how the apples are caught, because being able to catch one with any part of my sprite is kind of stupid. Finally, add some variation in the speed of the falling apples a bit more, this would just help mix things up and add an extra layer of skill. Like I've said, you could have done worse, but I think with a few tweaks here and there you could come out with a much better product.
