Soothing and enjoyable. It was just challenging enough without being frustrating. I like how the round task drove your theme. It was a great idea for the round. I ran into the seaweed after the happy ending because I hadn't hit them yet and wanted to see what would happen, I was just stuck in place. After a restart and running directly into them I saw your slick restart animation. Well done there. Might have been a good opportunity for linger for a few more frames though, make a more exaggerated failure sound or mom whale cry and then trigger the transition. Overall, great work.
