This is a nice idea, but there are a lot of bugs: If i move in the beginning, the timer is stuck at 1, and after a while there are no obstacles and the score went negative. Also, don't use the standard Unity background and a better color scheme. However, don't take this feedback too hard, you probably still haven't got a lot of experience with Unity, and even if you do - you will improve over time. Good luck with your future games and if you have a bit of time maybe check out my game too. Thanks! :)
