A very polished game!
Your team really put something special together! Everything from the audio, visual, and programming all felt really solid and refined. I loved the different art styles in the intro cutscene. The 'crayon' style is super cute and fun! And the pixel art portraits are super detailed! The background are also really detailed and pretty with all the decorations!
My only feedback would be to let the player 'jump out' of the peal mode. Right now if I jump while in pearl it just flickers the player's animation and keeps me in pearl. So if I want to jump after being a pearl, I have to time it just right. And maybe put some kind of save station at the start, so it doesn't replay the intro if you die before finding a save station later. Though I love the 'surprise' of the stalls for the save station, so cute!
Love the game and the puzzles! Great work!
