Thank you for playing our game! There is a bit of a fail condition (the sort of womp-womp sound that plays if you get a very low fill percentage) but I agree that other than the tutorial it's not a likely one, especially as you unlock more birds. We'd have loved to get some more mechanics in to spice up the game, if we had had more time! I'm glad you enjoyed the hand movement, early in development we had quite a few uncanny valley moments with the hand where the way it moved freaked us out a bit so we spent quite a bit trying to make it feel better, haha!
