The game has a simple main menu state with a background music, cloud moving and two buttons mostly [Start and Stop].
To make it more intuitive and appealing, here are some of the following things you can do:
Completely change the background to a whole different level
Add a how to Play button which can be clickable through both mouse and keyboard and should redirect to a new state which shows instructions on how to play it.
Add a Dino on main menu screen which can be moved left and right from the keyboard and jumps on spacebar. WHY? -> Cause I believe if someone wants to listen the main menu music and wants to pass time then can play with it.
Currently there isn't any monitoring of the High Score in the game. This is cause we don't have any I/O streams going on or making any calls that is storing that stuff in the server.
But this is a feature that everyone could appreciate !!
There are no birds as an obstacle in the game. So there is no duck feature in Dino if the birds come. Also we need to added randomness for spawning of bird or obstacle in the view.
