Absolutely blown away by this. In no time at all you've got all the basic functionality of the game in there, and it looks way better than the mockup did. Gonna be watching this one very closely :) :) :)
I did find a bug where after a few games, I started a new game and all the baddies and Redbirds were gone, it was just me and the train and the purple thing in the interior. Will see if I can replicate it.
