Would be nice to have a randomizer option for time between games - instead of immediately clicking through to start the next game, allow a time range set by the user, and then have a +/-25% function built in for every game so it's more random.
For example, have a slider that lets you choose between 1 and 60 seconds. Then, HR will further randomize it by generating a modifier of -25% to +25% each and every new game.
Will add a bit more to being more "normal"
