Pokémon Without Limits is a fan-made pixel-art game inspired by classics like Pokémon Red and Blue, but with a completely new twist. Set years after the events of the original anime, the Pokémon world has changed: borders between regions have opened, technologies have advanced, and trainers now seek more than just being champions—they seek to break boundaries.
