Totally random question, but did your sprite artist do the side character silhouettes as well or did you have someone separate do that? I'm thinking about putting together a short project but a lot of the side characters would be black silhouettes and I really liked how yours looked! If you don't want me contacting your artist though that's totally fine, but I figured I'd ask!
Ah, I'm glad you liked them - I know they weren't too popular with some people, but were sadly necessary due to budget constraints.
Actually, they were made by the same artist who did the backgrounds for 'Devil'.
They were made by taking the character sprites as templates and then painting over them and adding simple shading - the artist is a friend of mine and made them for me as a favour. If you message me on my support email, I can put you in touch with him if you wish.
