First off, I'm pretty sure this is just a demo of stencyl or something with the character altered... (I've played many a game on here with the exact same physics...) You don't seem to have much talent in the way of design. My suggestion would be to work up your skills. Do whatever it takes. If you can draw, scan it to your computer and make that your animation. This weird MS paint graphics stuff just doesn't do it for a lot of people.
So, Give it time and a real good effort and come back with something worth playing. Good Luck :)
