I'm not so sure about playing it online but, you could keep looking. What I suggest  you do is download the game to your cpu and ask a friend for the serial key. That's what my sister did.

There's no way to hack spineworld. I checked high and low and found nothing of use. Most of them are just programs that allow people to hack your computer and get your information. Just pay the fee the right way, and no cheats. Even if you did cheat that would just spoil the game for you.
