In this update I finally managed to implement character customisation. There were several complications, like character animations, which I had to resolve, but it's complete now. Character creator will show up when you hit "NEXT" in new game menu.
I also figured out how yyc compiler works and was able to improve game performance with it. This will be very useful when I start working on new AI system later. (yyc compiler is an "tool" for gamemaker studio engine)
That’s all for this update, complete list of new features, tweaks and bugfixes below:
