It's a good start. Though you should have it all one sheet of paper and the obstacles should be drawn, then you could fold over that! And also more paper related abilities like draw in items to help or use the eraser to get rid of key enemies or walls in the way. Maybe some scissors to cut things out before they fall on you or something. And the constant flow of scribbles gets kind of annoying so maybe limit the amount allowed out at one time. Maybe revise the story a little. Other wise It's your game, it's a great idea, and I'd love to see where you can take it!
