it's really not that complicated, a few steps of setup, sure, but after that it's just open Joiplay and click the game. And it's one app, the second thing is just a plugin to give it support for the engine that "Gomamon Trainer" is made with. You don't have to use it, was just letting you know a means of running it on your phone. The dev had mentioned complications with the android and browser versions in the past, so I offered an alternative "Foolproof" means of accomplishing your request. Apologies that the solution was not sufficient.
