Why do rabbits have such long ears? Well, they act as radar, helping the rabbit pick up sounds and avoid predators. They also regulate body temperature. I don't know, personally, I prefer my niece's theory that a rabbit's ears act like helicopter rotors and they can sort of hover around everywhere.
Which seems to be the general idea in Helix Bunny. Help your bunny fly around, dodging the evil floating skulls (trust me, it almost makes sense in the game). The cute, 8-bit style Helix Bunny ad-free with all levels unlocked drops from $4.75 to FREE.
