Design my first game site

Hey everybody.
I created my first game and decided to design a game site
I want to know your opinion.
Does the game fit the game idea?
Or do I have to change the design?

This is the link of the game on Android:
https://play.google.com/store/apps/details?id=com.naciryoss.WelcomeToDarkSide

this is trailer video:
