I see the movement already mentioned down below, so I have nothing to bring up as ciritcism. Simple and works, well done!

Can I ask what was this made in? HTML+js natievly? Scratch?

Congratulations on your submission! I like that the idea of the game is very simple and it's easy to figure out and to play. Everything works well. Sometimes the ball is a tiny bit slow to react to the mouse moving to a new location - I don't know if it's meant to be like that.
