Nice Game!
TLDR: Very Cute game and I congratulate you to your first JamSubmission!
Music: I love the vibes, feels adorable and fitting!
Art: I think the movement of the world, the jumping eggs, the Animations etc look very cute!
Areas for Improvement: Switching the Camera distance midgame is somewhat irritating, its better to keep the cam consistant because you loose the feel of how far and how high you can jump.
Player Movement: The Jumps and moving felt a little floaty, like you are on ice, wich makes precise jumps and movement a little harder.
Additional Notes: Your game reminds me of my first Platformer game I ever made called Hops - I remade it some years later as Hops 2 (https://thetra00.itch.io/hops-2) and I honestly felt happy and joyfull playing your game!
