So we originally had it where it would show you the specific number of seconds the roll would give you, but opted to go for a descriptive approach instead. My logic was that unless the player was intimately familiar with each difficulty of each minigame, the exact number would have no context for you.
For example, the falling game increases the number of platforms you get on higher difficulties. Perhaps we could have used both, maybe it's in parenthesis at the end of the sentence.
