I guess this is somewhat inspired by Citizen Sleeper but with a more stressing premise. There was tutorial in the game description page already, but having them in game (just picture slides) would definitely help.
Not understanding the mechanic too well I did spent all my fuel in the first two planets (by the time I understand the mechanic I'm on planet 2 with no fuel) and since no fuel, cannot end turn, and somehow enter into a softlock since ending turn require fuel ( I think? )
