It had a thought out story line and quite a few nice animations. I loved being able to play as a human and a bird. You had bird songs, which were unique and sounded lovely. I thought the idea of having to eat a worm to poop was genius(once I figured it out), but there could have been a more direct way for players to know. The thought bubble was just confusing at first, and it seemed like I had to put the worm back to eat it again, which seemed kind of weird. I did find a bug where the worm hole would keep moving around the screen(unless this was intended). Also I just got lucky and sang the two songs needed on first attempt, although there was no clue as to which were required.
