Not bad, looking forward to seeing more. Few things I would advise changing, the clicking to break the rocks should be one click. If not, make it so the rock don't bounce around as it makes it a lot harder to break the larger ones. Additionally make the large fragments glow if there is something in it. Avoid wasting time breaking them for nothing. Lastly, add a small white arrow to the tip of the cursor, while the paw is cute, it makes clicking and dragging during mining harder without knowing where your cursor is. Other then that look forward to new updates!
