Make bubbles appear

Bubbles will randomly appear from the bottom. You can pop them by
tapping or clicking on them.

I now have an idea for a game too (which will make the repo name weird):
Somewhere on the screen there's a cheese. Some bubbles will contain
mice. Your objective is to pop mice bubbles above the cheese. To control
where bubbles appear, you can tap and hold to use a fan that will blow
bubbles in its path.

Isn't that fun? :)
