I need some help with picking the right style

How could I use this type of character, and use this kind of platform thing, with jumping and stuff. I’m getting really confused, because I don’t know where to start with this, and until I know what I’m doing, I can’t start the jumping things. Can someone help out or give any suggestions on what’s the best way of making this?

The question you should ask yourself first, is what kind of game would you want to play with this kind of 3d manuverability? I’m thinking of bringing back the classics, super mario worl, what do you think?

Here’s the link to the preview.
