Hey um, hello there.
First of all, I did not make this.
This is "Aventura Pokémon" which literally translates to Pokémon Adventure.
This is a Flash game from 5 years ago that I got from Taringa!

Unfortunately the original Taringa! mirror doesn't work.
And yes I know it's shit but there's nothing I can do about that.
