3 weeks later I can say that Next Numbers was quite a success.
Recently we've even got cloned https://itunes.apple.com/us/app/find-next!/id791070906?mt=8
the main idea is the same, but here you have only 2 maps, click on numbers and not segments, numbers are so dramatically small. Game is pretty basic, no animations and between screens motions, no progress or anything like that. I wonder what framework did they use.
Anyways for Next Numbers sales are still holding. We're preparing an update based on users suggestions.
