i use the timer to refresh stamina and such, and im having trouble
figuring out how to test for that. i also have a function (reduceStamina) that I just can't get to work. it keeps saysing stamina is NaN for some reason
When you have this many options, you might want to accept them as an `options` object, but have defaults so they don't all need to be passed in.
