Hi all!
I have found that animation of the car.tank is looks slow when it rotated "vertically".

Hi, this is normal behavior of all rotated animations in Factorio and I don't consider it a bug. But it is up to our artits to decide.
Explanation: In our projection, Y axis is foreshortened (and parallel with Z axis). When we render rotations with equal steps, more frames will be in "horizontal" direction than to "vertical" directions.

EDIT: Actually, the problem might be, game logic behaves as if the game was top down (square tiles, character runs same speed up/down as left/right, ...), but graphics has tilted camera and this causes artifacts like this. I don't think we want to change how game logic behaves, nor to compensate for this discrepancy even more in art.
