That would be really easy !
The only thing here is that unless R0J0hound or Yann shows up , it would take you a lot of time to get the minecraft-style randomizing+saving system
It would be hard but possible ...
I have a little idea 'bout that but I won't be able to code it or achieve it ... ( School , Time , Personnal projects )
Another thing you want to know , the 3rd person view is only the 8-direction behavior with some animations to create an illusion !
Maybe , if this issue isn't solved before tommorow , I'll be able to help ya !
Cheers !
