Hi, so what is going on:
Rebuilding Unity 5 version, while adding new features, transition from Unity 4, onGui to uGui and learning new Unity/Playmaker stuff every day, I decided it is a good move.
I will use this asset in my game too so I'm interested it to be better and smoother as a base setup.
Thank you for your feedbacks here and emails, now I know what things I have to highlight in ReadMe docs/FSMs for more straight forward custom setups.
