Great game!
Art is cute, gameplay is simple, music is fitting, puns are butterly amazing!
I stopped after unlocking the chicken because it is becoming a chore to me. I would suggest that you add a little pop-up hint when the mouse cursor is pointing at an undiscovered item so it feels less tedious.
Also,maybe try to make the art pixel perfect the next time you use pixel art.
Good luck on your next game.
