У вашего броузера проблема в совместимости с HTML5
This is the modified version of my first game in javaScript, you can see it here(https://youtu.be/aa2oBDcCFVc).
What's new?
Added sound effects and background music, score count and game over screen.
The branches/obstacles are more random in length as well as in there occurrence.
P.s new look and graphics.
Stay tuned for more... @Irrational_pi (:
