Well, I just finished a 48hour game competition over at http://www.ludumdare.com/compo/category/minild/minild-6-minild-2/
for the "Mini" LD #6 January 9th-11th, 2009 and I want to post the result:
You can view the specific dev blog notes of this project over on my Ludum Dare page at http://www.ludumdare.com/compo/tag/train/

You are the Hero trying to reach the head of a runaway train to get to the locomotive. You start at the caboose and work your way along fighting off the bad guys who have taken the train over. You have to be careful not to fall off the train cars or get swept off the left side of the screen with a disconnecting train car. Also, don't get shot! You can get hit 3 times before you die.
* Use left and right arrow keys to move, Z to jump, and X to shoot.
* Use Game pad stick and button 1 to jump, button 2 to shoot.
BUGS / FEEDBACK:
I'd love to hear any bug reports or feedback as I'll be developing this game for a while longer still. I listen to all suggestions and do work on these projects long after the compo deadline. I will likely post an updated version before too long that is post-compo.
