Platforming with Gamepad Support

I know... the name is ridiculous. I never came up with anything better for this proof of concept. My first attempt at gamepad integration. Huzzah! It worked. Gameplay includes double jump, wall jumping, wall sliding, and portals. Made entirely with HTML, CSS, and JavaScript. Even the character and his fire animations are done in CSS. I might have to build this out into a full game down the road. Let me know if you think I should.
