Hey Sphinx,
I'm pretty sure none of the four solutions hidden there are working... :-/
Any possible problem here, or just me guessing wrong again? :-D
Please email me what you have tried to sphinx.rankk@gmail.com
Update: I've checked the challenge. It's working ;)
One entire day later and only valsa solved it?!? Are you sure it is a level 2 challenge? :-P
