I just read that you're not going to be doing the entire game. That's a sad thing to hear. If you keep this project as a spare time project it can totally be possible to do the entire game. Fangames don't have to have deadlines to finish. Still, if you're resolute about your decision than I'm sorry to see this end. Perhaps you can leave the source online for someone else to pick up?
