Bad news: I need to drop out. Good news: I still got something out of this.
The long and short of it is that I came in poorly prepared for this. Ultimately, time ended up being the enemy here due to trouble managing it. I also hit a wall today that ended up with my project getting messed up to the point that I would need to scrap it and rebuild it from the ground up. Finishing within the timeframe is unrealistic at this point.
The good news is that I got a better sense of my strengths and weaknesses than I had going into the jam. And I still have the my game concept that I can do something with. Not the result I was hoping for, but still valuable.
Next time, Ludum Dare. Next time...
