4. Instead of drawing rectangles in when playing. We now draw the characters! With randomly generated skins!!

Culling #bd56fa

When adding Culling to player rendering, I got an optimisation of 5ms->2ms.

Animation while playing

The initial phase was very easy. What I did struggle with was flipping the image. First, I tried flipping the texture themselves.

It did work but the offset of the bones were not in place. It was fine when going right, but when I turn left. It all turns bad, the 2nd video is a demonstration of that.

It took a lot of tweaks and black magic to find out that I had to also flip the anchor position and angle too 😭

Now it is working as intented :)
