I would like to ask: Is the sport Parkour simple?
I think the answer is NO.

There is nothing simple in that type of game that can be shown with just some few lines of code (simple code).

There are huge amount of aspects you need to cover to get a decent gameplay.

"But hey start up by doing animations for any possible move and climb that you could do in that game. Don't say I didn't provide some solution :P."

Just to be honest: Your gonna drop this idea immediately or soon enough. Judge me if I'm talkin bogus.
