Exactly, the sprite rotating is the only aspect keeping it on-theme. I could've easily added the lunge mechanic without the rotation. But its a nice detail and you can actually get different "lunge outcomes" based on how the bunny hits the floor or a potential obstacle. That gave it a tiny bit of emergent gameplay that even got ME surprised. I'm a big fan on emergent gameplay, stuff like BOTW and/or Spelunky. I believe its one of the biggest aspects that distinguish games from other media: giving a player a sort of sandbox with a lot of potential for interactivity between the parts; and letting them get surprised (and sometimes surprise the devs) seems awesome to me.
