This is a good game! NOT GONNA LIE! 
but please add more guns and improve the control interface and appearance!(make the joystick opacity less!) Also create more modes!(for fun)
Example:
-A simple deathrun map!
-knife mode!
-plant the bomb or defuse!
And add a slide option on the controls!
All in all the gameplay is fun there might be some errors but I'll give a 6/10!
