it's nice to see, that you are still interested in this game. It will probably take a while to the next update. Since the last upload, I have actually found a job, which takes most of my time now. But be sure that this project is never fully abandoned.
When I try to execute the .exe it doesn't start. Instead, there is the error, that the UnityPlayer.dll could not be found. (Could it be, that you created that game with Unity and didn't upload the rest of the builded folder?)
The only thing I found about your problem is the following: It could have something to do with your safety-settings: 'scan for threats' and 'install from unknown sources'. If you change those settings, it could work, maybe. If it works, please contact me again.
The Idea looks pretty fun. But when I start the game, i have a black screen and then the game closes automatically... (My smartphone runs on Android 4.2.2, if that helps.)
