I think the idea for this game is great, however the execution become unfortunately half cooked. The foxes spawn way too quickly in succession, the jump is far too light and needing multiple tries, and the bullet that shoot out are like poppy seeds, too little damage and no knockback. And no audio as well.
This could be a very entertaining game, but for now is just a existential struggle which your chicken never truly wins. That being said, very good start, and good luck going forward!
