Ah, this is super cute! Really giving me Untitled Goose Game vibes. I was totally expecting a loud honk sound effect when the seagull popped up on the title screen. I really needed the squawk button too, I think making the squawk mode an active trigger would have made it a bit more immersive.
I was little confused if there was an end, as things just seemed to continue. Some sort of round or score display could have been useful. The slow dismantling of the ice cream truck was amusing, though when someone took the nest I thought it was supposed to be over?
The transition of walking and flying was great, though I mean I usually flew ever where, having a bit more need for walking somewhere for something could be handy, though I'd want to move a tiny bit quicker on the ground. Maybe you could be squirreling things between your nest and another safer location?
It'd be great to see a post-jam version and what v2 would look like, great job!
