You are a king who likes to walk on roads. Unfortunately your endless world doesn't offer any roads. So you must create your own road in order to walk because you do not want to fall down. Also enemy castle sent some soldier to kill you - it is essential to avoid them too. There are also boxes in the world of "Roady Royal" you must collect in order to get metal to create your road. If you remember these words then you will be fine in the world of "Roady Royal".
A little glimpse
I hope you have some good time playing as a builder king! :)
