Hey there! First off, I really wanted to say that I love your game and I'm addicted to it! One thing that would make Falcross even greater was if you added an independent achievements outside of Game Center and once you get these achievements, you would get special unlockables.

I know some of these are already implemented like paid puzzle packs and online mode, but I think it would be great if y'all can add something even more fun.

An example would be: complete 20 puzzles and get a new set of music. Or play 45 hard puzzles and get a cool Easter egg. Stuff like this will get the audience more interested and I would love to see added stuff besides puzzle packs to make this game more interesting!
