The art is gorgeous and I love how you used the colour palette. Starting out with the egg/chick was adorable. Pigeon themed is lovely and pretty unique! The bird illustrations and animations are perfection.
I could only figure out the game play partially though - I guess it was meant to be like a tamagotchi, which were pretty confusing anyway lol.
I think hiding any options which weren't relevant to start with would be good? E.g. I assume you can't take the chick flying, but that just made it seem like the option was unresponsive. I did also have trouble telling which icon was highlighted.
When I was feeding him as an adult it was also hard to figure out how to stop? A highlight or arrow on the nest entry would be helpful. i was a bit scared I'd hurt him because he started making yucky faces when we were out walking then I realised it was a poop face LOL! I assumed he would poop whenever and we would just have to clean up.
I enjoyed trying it out, thanks!
