Only difference from the original game is I knew where the ghosts where. Having them as a blip on the minimap (even if it's only during the time while you're powered by the magic orb) would be nice.
If your having problems with sticky keys, I found that using an alternate browser worked for me. Beating the "Run Fast, Run Fancy" challenge was a relative breeze.
Got it on my 1,000,000th try only!
