Pros
-smooth gameplay
-good controls

Cons
1. When game ends and you get an option to either watch video or play again, you should
tell the player why the player should choose the watch video option. It should say what watching
the video will do for the player on that popup.

2. When game starts there is a notification about hiding the android buttons. I tried to press go but couldn't. It seems the game was loading during that time but it looks to the player as if the game is frozen or broke.

3. Needs sound effects
-when you squish enemy
-when car crash,
-when using boost, etc.

4. Level design which allows the player to do stunts early in the game.

Other
If you have the budget, the graphics and music could be improved. The music was OK but it could be better. Since this is another hill racing game alongside many many others, you will have to improve the graphics to have a chance to stand out among the crowd.

Hope this helped.
