Really beautiful and charming game in which you have to travel across the world in this strange vehicle which needs to be taken care of in multiple ways such as feed it fuel, release steam when needed, repair and upgrade parts, etc. Sometimes you'll stop to do some "puzzles" to open the way which boil down to press buttons in a certain way and that's it.
It's an interesting game, if you are interested check it out, it's only 2-3 hours long.
