Truly remarkable! It seems like a finished product that was done in under 7 days! You can definitely launch it as an official release!
I really liked how you took a known game and twisted it to make it fit the theme with nice little additions!
Visuals are outstanding! Game feel is amazing!
As for improvements, I agree with one of the comments that the ball should retain its position at the line, so you know where you are going to start next.
You can also add power-ups like black holes (That suck all that is around it) ever now and then, so it cleans up a bit the field.
Great job!
