You want to make a character where you can animate the player character.
You want the hero to be 16 Frames which is the total of Run/Jump/fall/attack/hit
I'm not that good an artist for an environment, but if it's a simple environment it's not a problem.
I can do this. I would say about 500, but I would make sure the quality and documentation is good.
