A few years ago I played a HTML engine pokemon game that your going into the enemy HQ in the casino, but I can’t recall the name of it.
The game has aspects of mind control, corruption, skin-suit, latex. You also fight a rocket grunt, and later you fight an incineroar; There’s also a room with a skin-suit of a pokemon that you get trapped in, same with another room of a massive pokeball.
Does anyone know the pokemon game that I discribed??
