I'm planning to write the script tommorow and Friday, since I have the story mostly mapped out already. After this week, I'll start designing and implementing the actual game engine. I'm scheduled to finish that (or at least have it in a playable state) by June JULY 9. That leaves me a solid block of time for content creation.
It is going to be a rough couple of months, but I want to get to the beginning of November with nothing else to do but polish things up.
