NYBBLE & NIBBLE
A half-byte adventure inside your Commodore 64.
There is a Nybble inside your C64. Find its missing half and become a whole byte. Guide a tiny glowing adventurer through a hidden world of platforms, walls and air-dash challenges.
Explore 60 rooms across six zones inspired by the C64 memory map. Chase 48 optional collectible bits, or concentrate on reaching the next room. A failed jump restarts the current room, with unlimited retries.
