I'm sorry but even the new update I'm still having the same problem, the buttons will not work at all, even though the game is active. (Side note: how to download in goggle drive)
On google drive, just click to download it, and it'll automatically trigger the package manager on your phone, installing it in a straightforward manner https://drive.google.com/file/d/1d9pn2n1hG2d20mp5g9c97CvGkjKGK2K1/view?usp=shari...
Yes, if you want an alternative link to the PC version you can download it directly from our Patreon https://www.patreon.com/posts/84799214
