This is really cute!! Great vibes :)
Unfortunately I wasn't able to play through all the levels since I got stuck partway through, but I absolutely adore the concepts/mechanics, visuals, and music (^w^)!!
To be honest, I'm not quite sure. It was one of the puzzles where you had to guide the ball to a bed, and I thought I had figured out the answer, but there was a point where the ball was dragged the exact opposite of where I thought it was going, and I couldn't find a way to block it. I'll try to take a screenshot or record what I'm talking about later today if that helps :)
It's most likely that the game is running fine, and I just wasn't able to figure it out on my first playthrough. I apologize in advance if that turns out to be the case!
