No, there's definitely somebody underneath the cloak, and he's pretty much human. He actually has quite an in-depth character, I just didn't say much about him because when I made the first post, I didn't want to give away the fact that he's a good guy. And it's true, the Little Humphis does change and I guess mature over the course of the game, but you meet Kymph quite early, so maybe that could happen a while after they meet. Hey, since Kymph is the only girl in the party, maybe the Little Humphis and the Shade Walker could fight over her. But that might be kinda weird, too.
Technically, I've been working on this game for at least 2 years. I've started making it at least 5 times, and each time it's better than the last one, but then I stop for a while and when I come back to it, I start a new one. But since I've posted all this stuff on this forum, I think (and hope) I'll actually finish this version. So yeah, I've got a bit of a head start. Don't worry, you'll probably be ready to make a demo pretty soon, even if it doesn't have all the final sprites and music and stuff, which mine definitely won't.
