You nailed the world build concepts of your game. You had excellent narrative pacing throughout the game. You music is also a stand out as well. As a platformer I think the controls felt a bit slippery but i feel you made up for it with generous sized platforms which gave your game Mario 3 vibes.
Also i am puting together a best sound track ost for this jam and id love to include your game on youtube if i have your permission. Your music really captivated me in your game.
