Builder Birdy - free puzzle game launched on iOS - feedback wanted

Yay!! I have launched my first game for the smartphones/tablets. Its a puzzle game that challenges your brain to arrange and match bird house blocks and build birdhouse colonies!

The link for downloading on the iOS app store is

This has been a sort of soft launch as I have not started any marketing yet. I am trying to gather feedback and release an update before marketing the game. Any feedback from the Corona community would be very helpful.

Here are some screenshots:
