FOOL: Add an option to make the High Priestess enchantment easier

[dfabulich]

In The Fool's Errand, the High Priestess enchantment ("The 99 Enchantments") is an extremely difficult twitch-reflex challenge, in which you have to click on 99 numbered buttons. Once you click on 66 buttons, the buttons start moving around; when you get to the last button, it moves around very, very quickly.

I think it would be great if the game had an option to make it easier.

I think this arcade challenge is not accessible to keyboard users as it currently stands.

Here are a few possible approaches I've considered:

1. An option to prevent the numbers from moving around at 33 buttons
2. Or an option to make the numbers jump around slower
3. An option that would make it possible to win by pressing a keyboard shortcut to select the next button
