Partly as documentation, also partly for my own reference and for everybody else, here are some images that I think work well with the train setting. I always imagined it being quite a posh train (as well, it has a bar in it) but there should be a variety of images here to get people interested.
On a side note before I post the images; bar a few minor issues the engine is complete. The code for things like puzzles hasn't been done but for the first several puzzles I know exactly how I'm going to do those so the engine is pretty much complete.
Also while I'm at it I should point out while trying to get one of the elements of the engine to work I cam across a plugin for flixel called flixel power tools. (http://www.photonstorm.com/flixel-power-tools) Honestly its mostly just for special fx and stuff like that but its got some interesting stuff in there which could give us more ideas of what we want to do with the game. Most of the stuff I already know how to do in flixel but the special fx section is pretty interesting.
Anyway, on with the images.
