Hi! Thanks for supporting our project. Unfortunately no, as our game just respects the limitations of the Game Boy as an aesthetic, but the technology used is actually Unity. Someone contacted us to port the game to actual Game Boy hardware, so that can be something in the future, but we won't make promises as this is an independent developer (as we are haha) working on it in their free time.
That said, we are working on the Android version of the game which would make it playable in a wide range of devices that have the Game Boy / Nintendo DS form factor.
