Hey, thanks for taking the time to make an account and write your review! Really happy you think so highly of it. The next game won't be Helltaker related, but will be Helltaker inspired. But don't worry, I'll keep making HT art and comics at my pages.
What you speak about is not exactly a "bug". Modeus´ charm skill can only be used one against other demon girls because it would be too broken otherwise. But it is my fault to not make that more intuitive. ^^´
