Could you remove the unpolled eyesore that these footprints are? Yeah the rooftop courses are a little hard to figure out, but that's only for your first couple runs. We don't need footprints, npcs, and signs all over the place. I don't think anyone is opposed to making the clickboxes and paths a little more intuitive. Footprints all over the place isn't intuitive.
Remove the signs, remove the footprints, replace them with something thematically fitting, like worn out roof tiles or something.
