Scaffolding: Concept Review

The game I've chosen for my project is one that I've developed called Knightborn. 

It's a 2D side-scroller that only needs A & D for movement and the mouse for LMB and controlling the cursor. I chose Knightborn because it's something I made and I think an action side-scroller fits the scope of this project; its simplistic controls will allow me to be more creative and create a controller with full support for the game and will be less limiting to the layout or method for the controls I'd want to use. An alternative controller, if done right, could set my game apart from others and make it more unique.
