The draining energy is definetly intentional, the people and the travel demands energy, even if you don't take any decisions.
And about the english grammar and spelling, we're from Brazil so English isn't our native language, we're looking into it to fix as soon as possible, since it doesn't alter any mechanics and anything "critical" in the game, it seems like a fair fix.
Thanks for the feedback and we're happy that you liked the game!
