I did try this level but since I'm not a fan of hidden and I have no time (more than 30 seconds) to get the right combination to release the Ps, I just moved on.
@gmacpro Thanks, I think hidden levels or patterns will not get any likes/stars here, I'll not make any levels like this again hehe...
@Bry.C - If the Ps were released then the level is fairly easy. I'm thinking your spoilers will not help as that portion is obvious.
