Hello Mehad,

I played your game, I like very easy and intuitive control. The characters are very visible and stand out from the background.
In general, the game is pleasant and friendly, but it gets boring at level 3. To make the game more attractive I would add character statistics development and various weapons so that the player could choose his favorite weapon, in addition the game would be more difficult if you added reloading and collecting ammunition.
If you add issues that I raised to the game, the game will definitely be better and you will succeed. Good luck!
