Tip: When determining a time limit, remember that players won't be as familiar with the level as you are. If you normally complete the level with around 100s left on the timer, others might run out of time on their first try.

This sounds like something that would play in, not only a hills/mountain setting, but also in a more western setting, if the hack has it. I think about things like the ol' Wild Wild West when listening to this.
