Well, I have thought of that but my problem is that it is quite a
large sprite with the shape of a parallelogram. It is not possible
to compute that of multiple rects.

The graphics would be possible. I am thinking of a .collision method
that would check the pixels; if they are coloured, there is a collision...


but I have to go now.
