The dev a rip off merchant. The story has been done, so what did he add. He made a weaker mild version. Then it's wahaaa, no subs. He'd get subs by releasing content, not little drips of it. Bigger updates, and if it's demonboy be a demon or something. Instead of not releasing much of it and it being rather vanilla.
If I remember correctly, dev said he'd also make an announcement with the update. I thought he would talk about not getting enough support to continue. Did he say anything? If he did, and if that's the case than he really needs to step up his game to get support.
