It's time for a new unlocker. Google bans unlockers for games that have in-app purchases for the same goals. Since most games nowadays get their income from in-app purchases, it has been difficult to find new games to unlock.
Then I found the Final Fantasy series. That's a great series of RPG games, and I found myself stuck on several occasions, whilst playing Final Fantasy III. If you are in the same position, my new unlocker might be the tool for you! Just use the unlocker sparingly, as you risk making the game too easy. Still, I can highly recommend the game, if you love a good RPG.
