This is really nice! Restarting at the end and seeing the difference in color from start to finish was really surprising, I had no idea it'd changed that much. I really like that the trash in the back of the boat is the actual trash you picked up, it reminds me of katamari damacy. I think it'd be cool if different parts of the level had different types of trash so you could tell where you've been from the contents of the bucket, or maybe have a score bonus for dropping a load of only plastics or only metals.
