The controls for the movement feel too much like they're sliding, especially for turning, like there's no resistance to turn the direction of where the tank is moving. This is not ideal for button presses (as opposed to joysticks / analogue sticks), because button presses are only either 0 or 1, that's why the turn speed is so fast. If the direction controls are through a controller instead, it would be easier to have more control about how fast the turn speed would be. Aside from that, there are not a lot of co-op games out there, so this was a bit refreshing.
