I simply love this game! I wanted my game to be pure 2d with extremely simple graphics but got no idea how to achieve it.
But this one. the poly outer line that only serves the art. the "transparent" BG with a comforting colour.
I've seen scaling with scrolling but this is the right way to do it.
Now it's in my collection. I need to check it before my next project.
( Is this your first game? Since I think the art and creativty really requires experience )
