In the game, it was about a small figure to constantly drive his train / car / means of transport and repair if necessary. You had to refuel again and again fuel that you found on the way. The game was quite short, so it was about 3-4h and it was really hyped, especially on Twitch.
The mood of the game was rather gloomy, and designed in dark colors
