Not worth 20 bucks, as you can complete it in 2-3 hours. But on sale, it's great.

Atmosphere from the art direction and sound design are fantastic, and the gameplay design with train survival mechanics is unique and streamlined.

Pretty good one. Short but sweet.

Good game.
Open world, exploration.
some light combat.

Slight horror.

I've played it through twice now.
Its important to remember that this is an indie title, made by one person.

It's also a very atmospheric game, so the worst thing you can do is rush it.
take the time to explore and do ALL the side quests.
if you do it right it should take you about 5 hours to complete. (any less and you probably skipped/missed something or rushed it)
