Well, I drew them from scratch, but obviously I was copying the distinctive face shape of the Cave Story sprites when doing that. That's kind of the point, you know? Of a parody?

It's very nearly 0% originality, actually, and about 50% Cave Story (hence the name) and 50% Touhou (hence the other half of the name).

ptoing: Yeah, I know, I was just derping around. I usually try and go for authenticity in my mockups, but not this time. :]
