This is really great! It feels like such a cinematic story, really well done and polished!
The visuals are great! Although the train kind of looks out of place, everything else was great! The start and end credits were really well done.
The Gameplay itself feels very linear, and not as open to exploration as I would've hoped. Like there is only one way to beat the game, which is uncharacteristic of the genre. Although I might've missed some things.
The music is amazing! Honestly one of the highlights of the game, along with the intro and credits of course.
This game can definitely be expanded upon! Make the train bigger! Add more endings! You can easily make it a full release.
