The art for the main menu was lovely, I really liked the bubble design for the start button! Although the art style throughout the game felt a bit inconsistent, ie: the character designs being a different style to the environment.
The cleanup mini-game was quite easy to learn, but I found it got a bit repetitive after a while, and it took quite a long time to load for me, which interrupted the gameplay.
It could use some more polish, but the idea is sweet and being able to turn into a seal was fun!
