Can i instead of having a background image, have a pixel level where the player can move around and interact with objects in that level? With of course respecting the elements of a horror visual novel?
Hybrid VNs are allowed but the gameplay must be supplemental to the visual novel- it has to be a visual novel first and foremost. Some hybrid VN examples where people can move around and interact would be Ace Attorney or AI: The Somnium Files.
