I still am! Though university is pushing the hell out of me... Just today I had to deliver three work proposals for really teoric stuff... But I haven't forgoten it and I'm working on the background. Although I haven't posted updates, I have some things that will come in not much time (about one or two weeks :P) But yeah, 8-dir movement will be possible. I'm actually trying to make 8-dir AND more frames. Because, after all, with such details, 3 sprites for the movement seems kinda little. But that will take some more time. In the meanwhile, you guys can post some feedback on my thread, because I'm still needing for feedback to finish the other arms...
EDIT: although I'm making an ISO HK template, like gratheo said and really well, do not expect it to be compatible with existing or future resources. I may work on resources compatible with that format, but most of the folks will, and actually should, to post stuff for 4-dir only.
