Congrats, you have beaten me at my own game!
That was real sneaky the way you got from #34 to #35. It took me ages to figure out how you did that.
I'm particularly impressed by how you managed to skip Pluto's first level, and that allowed you to come back to it later. It was polite of you to do all your merges before Pluto appeared.
You can remove 2 snapshots by making #21 more efficient. Good luck!
