Should my game be a visual novel? I mean, if the game only has text, can I only use it as text (using characters to make words and sentences)? Can I create a game with graphics made up of characters (like in the screenshot)?
The game cannot be only graphics (even if the graphics are made up of characters), and the gameplay must consist of interaction with text as text (so something like a platformer or top-down RPG where the focus isn't interacting with the text wouldn't be allowed).
