There's a detail I love in ZeroRanger but it requires some setup. In stage 2-2, there's a secret bunny girl that shows up if you destroy a box quickly enough. Her sprite is a bit larger than the sprite for the player's ship, which raises the question, "cute Easter egg, but wouldn't she be like 10 meters tall?" The devs decided to answer this question with a definitive "No that's not just an Easter egg, she is diagetic, and she is actually 10 meters tall."
An important part of ZeroRanger is that everything is diagetic, including game overs, continues, high score tables, and the giant bunny girl in the mines.
