Sky High trick

Hey Jammers! I think I found out what's the trick in Sky High game. If you want to get cool item, you must deserve it. So, you must try to collect ALL gems, or as many as it's possible. I collected 229 gems and I got a freedom helmet. And I also realised that the more gems you collected, the harder level becomes, because when I played the game before I collected around 160 - 180 gems and levels weren't so hard. I'm going to try to play again and try to collect all gems if it will be possible.
