Pretty fun
Not a bad game for passing the time however ther eare some minor things u could do to improve it.
firstly i round my friends at the moment and his pc is not super but its not weak and even on low graphical settings it does slow down sometimes i beleave u need to debug it or something make it more smooth in running.
One of the main anoying things is The music is soo repetative and it suck ass, no way to turn off while in game aswell, i turned off at the title screen but after the first mission it turn'd it self back on >.<
Maybe make so u can turn of during game or make u have a selection of music or even find one decent tune.
how about some sound effects? you knwo for the gun firing and the explosions.
And one last thing weapons why not make it so u can upgrade your tank more, that weapon/shell looking upgrade did not seem to do anything maybe up the rate of fire but that was all, make so u can upgrade weapon to have dual barrrels missiles and other such things.
In all not a bad game tho.
