I had a few setbacks on the way.
I appreciated the change in backgrounds as well as the music for them, and that the song choice felt appropriate for the current season.
The concept is simple but definitely becomes more difficult as more and more characters (or bugs, I guess?) are included.
One thing to note is that, since characters only move left or right, when there are several of them in a line it's safe to ignore the ones in the middle since they have no where to move to. In a more fleshed out version of this type of game, I'd suggest adding vertical movement possibilities to help alleviate that and to make things just a bit more complex.
