This was lovely, well done! It took me a while to realise that I think the cursor paw's cursor point is in like the top left. Until I realised this I kept having trouble clicking on the stars, so I think the cursor could be improved to be clearer where exactly the cursor point is.
It had loads of levels which was great! I was really hoping there would be a new mechanic introduced though to spice things up. Would be cool to see what you come up with regarding this if you develop the game further.
Nice work!
