It seems it is really outdated but still this is a good hunt @teamhumble. My comments below :

Pros :

• It can be your alternate option to play pokemon game which you have a controller that is really the same with Nintendo controller.

Cons :

• It seems that every execution that you do to the controller, whether it would be just start or using directions, a QRcode will appear so you could pay for a Bitcoin which i think is not a good game to play with.
• Pokemon version is quite old and classic in which if we compare to the new generation of games,it would be a huge different between them in terms of graphics and gameplay.
• Web based type Pokemon game which i think is a bit slower compare to paying with an emulator or a console.
