It's made well content wise and Fun wise, quite an innovative idea too, something like a combination of temple run and subway. One issue though, the joystick is very rigid, either it goes too fast or doesn't go at all. You can fix that by making it a distance scaling for UI using some math instead of using rigid velocities. Then it would truly feel like a joystick instead of 2 random buttons. And I think that's what is better for this game. But still even on that, it's a game that is already very complete, playable and fun. Nice Job!
