Solid, interesting premise, great graphical style! I found it a bit too dark. I grabbed what seemed to me lots of wood and then ran back to my train as soon as I saw zombies closing in only to realize I had way too little wood. I think I misunderstood the intended playstyle and was coming at it from a "peek out, grab a little, duck inside, move on to a zombie-less zone" angle, but it seems more like you're supposed to actually fight the zombies? Definitely an interesting premise - it's like Snowpiercer but zombies instead of climate change - that I'd have played more of if I weren't easily spooked by menacing ambiance in a game, haha. I could see this being a KILLER concept for a multiplayer PvE game.
