I too have glitched when getting on the train. In fact I got stuck within the train model and couldn't get out (0.5-FIX)
I've seen mention of Unity being used for this project, is that correct? There seems to be some comments suggesting this is built using minecraft but I guess that is incorrect?
It would be great to see a roadmap of what you are planning to add to/update within the game. Also in terms of textures are you planning on updating the placeholders for the buildings, people etc or are you going for this look as a design choice? Personally I like it just as it is :)
Anyway, I've been following your project via the video's on youtube and finally found my way here and download the game. Appreciate that this is a work in progress but you have nailed the atmosphere! it's brilliant!!
