Hi Melty, it's not abandoned.
I'm trying to work around some setbacks I've had in my personal life. In addition, the game has become quite complex, I've lost my writing partner, and Episode 5, which is taking a while to be released, is really huge. It's probably more than double the size of any other update.
Just this week I managed to take some time out to dig into the code, and I've made good progress that will free me up to render the last few scenes.
Thanks for your question, it made me sit down for a while and write a brief update. I'm going to take advantage of the fact that you've made me put a few words together, and use this info in a post so that anyone who's interested can also get an update on the progress of the project.
Cheers,
