You know... I don't really know code... but couldn't the story technically continue and later images added?
From everything i've read so far from Hreinn, their development cycle goes something like this:
1. Discuss the content of the patch.
2. Nomo starts drawing, writer starts writing.
3. When those two are finished the coder compiles the content into a patch.
4. Test and release.
Now, i must say again that i don't know much about coding, so anyone with more knowledge can correct me on this one, but as soon as the plans are made and Nomo has some sketches or the writer has some rough scripts, a programmer can start coding already with placeholders and just quickly replace those with the actual content when the artists are done.
Even if the coding process legitimately takes a couple of months due to some kind of difficulty or a lack of available time, the task itself can be started long before everything else is done. And so far i've not seen a single indicator of that happening.
