Great job! I thought the pacing was perfect, with the visuals and text having exactly the right amount of detail. All the elements felt harmonious, and it made the overall experience remarkably cohesive.
One technical note: When I tried to fullscreen the game, it stayed at the same resolution with a large black border to the right and bottom of the game window. I switched back to windowed mode, but because of the resolution the itch.io info bars overlapped the top right of the game window. They actually covered up the heart in the top right of the speech bubble stage. Took me a while to notice, but eventually I figured it out.
