Hmm... I don't quite get the theme into the game. But the way the game is played is very relaxing. Personally, the music stood out among everything else. I was hoping there would be sound effects when the player sucks a garbage, like a woomp of a vacuum cleaner. Same like nobbele, nothing happened after cleaning up the second level. You had a great way to explain the player on how to control and play the game. Good concept.

Maybe instead of the win state, you can try creating the game to have infinite amount of bad thoughts inside your head. Like, it spawns with a random size and a random position in a second or two. I'd like to also point out that the game is very open, like there's no limit. Players can easily get lost as if they thought there's more around there. But if not, I suggest you should create a barrier or maybe a way that the player loops to the other side.
