Hello!
Thank you very much for your recommendation! My problem is that I don't know how to convert the game to apk. If I knew, I would. I'll investigate!
Regarding the absence of buttons, well, in theory, RPG Maker, the engine with which the game is made, comes ready to compile the game for Android and allow you to play without any problem, since the screen is touchscreen and you have some how many buttons And, even if I convert the game to apk, I don't know how I could fix that.
