Nice little game.
I ended up stopping once I got to 100 because it didn't seem like the difficulty was ramping up or anything new was going to happen. If you work on it after the jam, might be fun to add some new elements as your score gets higher.
I also started just throwing things in whatever recycling bin and it seemed to work the same. I don't know if that's a bug or by design.
Otherwise, nice game. Smooth controls. Everything worked. I enjoy the peaceful gameplay.
Cheers
