a simple challange?

I need something to do for something to do but not too complicated it can be anything but not building a game?

Make a script where when you hold z It will charge a ball that gets bigger and bigger. The bigger the ball the more damage it deals.

When you release z or it hits a max size it will launch forward.

If you want to get a bit more advanced make it so that ball ( Which will be a Part ) and will give the player who launches it the kill if they kill someone. A little hint: Make the ball's name the players name.
