Nice.

If someone can upgrade it than do it but tell me where I can find it

You can add a little thruster on the shooting pin with 150N of force to shoot out the ball. I'm talking about the pin we need to carefully pull, overall the game even as a teaser is being done very well!

You can also bind that thruster to down arrow key so it won't make a problem

f button, I checked

but you need to hold it for a while and then after 2 secs let it go

If someone can make me a shooting part for my tanks I would be very thankfull for link to it.
