The game and its sequel Custom Robo V2 were re-released on the Nintendo Switch Online + Expansion Pack in Japan in July 2022.

In order to open the robo, the player must quickly press buttons and directions on the control stick.

Noise, the developers of the game, said that their inspiration was the childhood fantasy of being able to become the action figure and play out battles.

From this idea, the Custom Robos within the game were designed to be similar to real life Japanese model toys, with interchangeable parts and bodies able to move and pose with a limited degree of rotation.
