So I was refactoring the code for WiM so it can handle different resolutions. In this test I used twice the standard resolution (the HUD doesn't change yet, that's why it's in the upper left corner). The ball stretches itself a bit, when it hits a wall. For different resolutions the factor of this stretching is of course different.
So I wrote a bit (not entirely sure, if it will work) and well that's the result.
Ignore the blue hitboxes and the wrong display list of the stage.
