I've been thinking of writing a FNiA-FNaF game/Novel myself... but I'm no artist or game designer so I'd just be writing the choices, story and secrets
2. Use assets from horrorweld if u wish I can always update them for missing things (textures backrounds). As far as I remember on the EspyAspect Deviantart he sayed that ppl can use his assets to make game. Just credit him. Or use Mairusu assets. Ur choice
I rather be a writer of the story/choices, I'll leave that stuff to the professionals mate... anyway take your time on your solo project and this novel
