My game had quite a few nasty bugs on release which I have recently fixed but my biggest regret was that I didn't get to do more for the characters randomization sheets.

Heads: Faces:

This was the bare minimum but suprisingly it allowed for quite a lot of variation by manipulating the textures in the shader with scaling and hue shifting.

Since then I experimented with more. Adding rotation, disortion, offsets and background colors randomization. Still the same 2 heads and 2 faces though.

Are you heading over to my game and invest your time for great funs in returns?

The only thing you have to do is to acknowledge that its Definitely Not a Pyramid Scheme!
