Thanks for writing this up, it is always interesting and saddening to getting a deeper look at indie development on the app store.

It seems like more simplistic puzzle games like these have potential to completely blow up, but the market is also completely flooded with them. And I have found that it can be difficult to find quality in the genre. I would imagine that games that have heavier focus on art and polish can make a world of difference. It seems it gets attention from blogs/review sites and more probable for Apple to feature them.

Regardless, it is frustrating that your hard work that goes into these games didn't get the attention they may have deserved. Keep up the great work and hopefully we hear back from you soon about a monetarily successful game, whether that be in the app store or elsewhere.
