I'm making it a vertical auto scrolling game. Think Flappy Bird, but vertical. The player is always climbing up the wall/rocks/cliff. Plan to implement a stamina bar, so he will have to try and reach a certain object to refill it or he falls. There will be other objects to avoid such as thorn bushes, birds, enemies, etc...
I guess I could get rid of the 8 directional behavior and give him the platform behavior to see if it works.
There won't be any platform type objects to stand on, as he is in constant climbing state (think Spiderman climbing up a building with back view, almost like crawling position).
I also still need to figure out how to make the background image repeat as it scrolls. I have the screen going, but the tiled background (on a separate layer) ends and then he is just climbing on a white background.
