Would you have preferred WASD for controls, even if the tank can't turn 180°? Thanks for playing and for reporting the sound issue.
I think so. I feel like the current controls are better suited for games where you're not limited to 90-degree turns. Maybe removing the 90-degree limitation is the solution.
One cool thing you can do is hold A or D and almost spin in place. I wonder if people ever came across this technique with the current controls.
