Maybe an arrow of some sort pointing into the tube? I knew to try it because Mario uses warp pipes, but it didn't seem to work at first as holding s, my first inclination makes the game bug out and the "interaction" text seems to be very faint at first. Perhaps a background image at the start or one of those little instruction boxes if you want to make more reference to Mario with a pop up saying that s is the interact button?
Also, is there any content besides wandering around?
