The puzzle requires a bit of brainpower. You can take your time and enjoy it—it's really nice.
It's nice and stress-free that you can try again as many times as you want. There are hints available, too, so it's great that the game is designed to be accessible even for people who aren't great at puzzle games.
Personally, I do feel like it could have used a little bit of music or sound effects.
I had fun. 🙂
