How do i fire gun to kill viruses [SOLVED]

[craftalife]

I can get the gun in the maze but can't figure out how to fire it to kill all the viruses. The only control I see is the virtual joystick to move myself. This is inside the robots head. On an android tablet.

I'm having the same problem on my Samsung One Note. I got all the blue bits, but can't shoot the bloody viruses. Grrrrrr...

What did you actually do when you were trying to fire?
Did you try to double tap?
MAYBE there is a fire button which you didn't notice.

I know this is an old post.  However, on the android tablet, there is the navigation area on the right side of the maze and there is also a icon on the left side that shows the gun when you get it.  Tap on the gun icon to shoot.
