If you think about the same thing as i'm thinking about, im thinking about that too!
I'm thinking about an object where you can draw sprites with diffrent images depending on if there are sprites around them. For example, ground sprites would get grass around the edges that are not surrounded by ground.
I think i suggested a "Level Editor" to construct too. Both construct and it's concurents are terible to use for level design, and an in built level editor, where you can ad the objects you want, and use diffrent tools like fill, pencil, or just klick out the objects would be wonderful.
