I tried your game on my Sony Xperia Z1 running Android 4.4.4.
First time I started your game I got a long loading screen and then the screen just turned black. Not sure why. The second time I tried, this time in portrait mode, then the game loaded but I could only see half a menu due to it not being made to work in portrait mode. Third time I got it working by starting it in landscape mode and this time the menu eventually loaded. So first thing you need to do is lock the game to landscape mode only.
Sadly I must say your game in its current state is not good at all for mobile. First of all the menu items are too small and not very intuitive. As I start the game the first time I have no idea what I’m supposed to press or what they do. On top of that the interface feels slow and unresponsive.
I pressed “Bike” and it gave me complicated options that I didn’t know what to do with. I pressed “back” but it took so long to go back that I actually pressed back again and accidentally exited the game instead.
After starting the game again I pressed “Logs” since that was the first option, but then expecting to see some debugging log files or something (because that’s what I think about when I hear “logs” 
). Tried to press a few buttons but never understood how to play, it just kept giving me a long message about my stamina or something.
Mobile games typically should be self explanatory and not so complicated to play. And if you need to do something more complicated you better at least have a tutorial for it.
The game graphics was so bad, from what I saw the logs had no textures just solid gray. Also when I pressed “blocks” basically everything was just a solid gray color except the biker.
The whole game feels like a hack from PC to Android to make it just barely work (and I suppose that what it is too). The only person I think would spend time playing this would be someone who just love the game for PC and want to play it on mobile too and doesn’t care that it’s very ugly. But even that’s a stretch in its current state.
If you want to actually make people play it on Android you need to remake the design of the UI, making the menus bigger, more intuitive and prettier. Consider removing or hiding advanced options so the user isn’t confused and make sure the user understands how to play your game.
Also the graphics really need to be fixed, you can’t have just a solid gray environment.
I haven’t tried your game on PC but I can see how it would be a whole different experience there I only tried your game for a few minutes, but honestly that’s what mobile users will do and they will judge your game on the first impressions just like I have done here. So maybe beneath the surface of all this there is a fun game but I and most other people would just never bother to get ourselves there.
Update: I looked now at your screenshots. Your game looked nothing like that in my phone. Your biker was textured and everything else was solid colors with no textures. Whatever shader you used to make the black lines effect never executed on my phone.
