This is the last kind of feedback I thought I'd get! It's too easy, you brainiac?! :D Okay, thank you, that's noted. Not too easy and not too hard is a balancing act, but guess I'll just do my best with it. I probably won't add hints in advance, but maybe I'll add a comment from coach saying that "if you can't find it, I'm sure someone will help you with it". That way, the player gets a hint that it's a challenging puzzle, and that help will be coming if you need it :)
