I made this background for a game separate from Mnemo but I realized that the room needs TWO beds instead of one. Instead of just editing it, I might as well redo the entire thing and fix the lineart a bit. I don't think anyone would actually want to use this but just in case...
There is only one variation of the background and I don't plan to make another version unless it's specifically requested. The size is 800*600, the default Ren'py size. You can download the full sized image here.
