I have found my way to Snarl and boy was it a ride!
I really liked the harder puzzles, but it left me randomly clicking for quite a while. As much as I like a challenge, I thought that some "locks" felt a little arbitrarily.
Yet don't let that stop you from making those puzzles harder! Maybe just add some hints eluding what to do next or what you missed for dumb old people like me :D
Hope to get Abscission and Carnival in the near future~
