The polish on this is amazing, so well put together. Well done!
Art and audio come together so well, full menus and tutorial make it feel really complete. I don't know how you find the time! :)
As others have commented it is very tough though, I really struggled where you had to hit multiple targets with a single throw. And if you hit anything you go back to the start. (I suppose this fits well with the fragile theme.) Perhaps an easy mode where it's more forgiving?
