I enjoyed this! I think the little eyeballs getting bigger when you click on the birds is great. I think you did a great job with the collisions - a little leeway so the game knew what I was doing. It's cool you can pause and mute the music :)
Did you do all the art and music yourself? I like that the open pond is an option. it's a soothing background when I get distracted by something else. Great job!
