The bird is adorable! The ui often seemed to break? Buttons just wouldn't work. I couldn't really tell what I was doing 90% of the time. It took me a while to realize that the bird was chopping down trees or something? Maybe I didn't get far enough, but I wasn't able to find how you fit the theme into the game? Unless it was the ui breaking.
Some audio cues would go a long ways to help make the game more clear. It'd also be neat if there was a way to positively reinforce the bird's habits, instead of hitting or scolding it.
Good job on the submission guys <3 Best of luck with future projects
