Hey dev. Thank you for so cool game, really like it. I want ask a question... Mission about railway station is last at demo vers? bcs i dont know what to do there. Hope u will work further  and finish this game) Good luck.
P.S. It will be very cool, if u will add coop or online mod for this game)

yep that's correct, railway is the endgame for the demo. In the full version, from the south of railway you're supposed to "teleport" to Station-11, which is what I'm working on :)
