Welcome aboard the Mastodon Express! The most luxurious train built in the likes of a Victorian mansion. We encourage our passengers to explore our fine establishment and uncover the mysteries long forgotten. We do apologize for the supernatural and eerie atmosphere; it's expected with a train as antiquated as the Mastodon. Ring the bell when you wish to exit, and don't forget your baggage (including any emotional baggage acquired during travel). Thank you for choosing the Mastodon Express and have a safe trip!

For fans of puzzle adventure games and escape rooms.

I really enjoyed this game.  Is there a walkthrough or list of endings somewhere, or is there only one ending.  My first playthrough I didn't get all the handprints before leaving, and I got the "free as a bird" ending.  The second time, I found all of the handprints, but I got the same ending. 

There are currently two endings. The second ending is trickier to unlock but finding all handprints is necessary to get the next clue. I will write a text walkthrough or upload a video showing all solutions soon. I'm glad you enjoyed the game, thank you!

Gracias por la descarga gratuita, pero a la hora de ejecutar el exe dar error dll biblioteca de sonido 3d.

Gracias de todas formas.

Very entertaining game.
