How could you possibly cheat on something like this?
Anyways, it would look nicer if, instead of two buttons and some text to signify if the music or hints would play, you could use a single button that changes between on (a speaker with sound waves) and off (a speaker without soundwaves and an X on it).
Yeah, you can also jump when you should have slid, and still make it. It's really hard to do by mistake, and pretty much impossible to do on purpose. Consider it a lucky break.
