There is an "again" button at the left/middle, but I'd like that when I press the current number at the bottom it runs again the simulation too.

The parabola graphic at the end is confusing, perhaps you should draw the parabola.

Also, the share in the last slide is annoying. You may add a fake 20th slide so the 19th is clean.
