I really like the art style and platformer gameplay. Nice that you supported a gamepad. It did seem quite hard (but from reading comments below I guess that is what you were going for). I would have liked a little more range on the jumps and better control on the 45-deg slopes. Also more range on attacks while we're at it. :)
You might like to try our platformer game - the jump mechanics are quite different though (to go with the main character design).
