How hard would it be to make a game similar to Yoo Ninja

I have little to no coding experience, but I have what I think is a really good idea for a game. The gameplay would be similar but not a clone of Yoo Ninja

 

first you need have the basic physic for the ninja
like jump, reverse gravity,
after that you need create maps for your gameplay,
actually it's not quite difficult to do,
but you really need understand for the features of unity3d,
do a basic for movement first then continue for the other features.
that my opinion.

 

Hi,

I am interesting by the infiny map of "Yoo Ninja", how can I do the same on Unity 5 ?

So an infiny runner game with an infiny background map creation, but not random creation as "Doodle Jump", but a real position (so same map if I restart) like "Yoo Ninja". Because I can do it if I put all gameObjects in the scene, and I turn them visibility to "On" when the distance start to be nice (and turn to "Off" the old of them, not on the screen), but I will have a huge scene and a lot of gameObjects and I hope it will not create lags (or other slow down) on mobile.
Their is an other solution ?

Very cordially.

 

Mr Blue did you create your game like "Yoo Ninja"? If yes, please write details.
