Nooo, they all should struggle! I'm kidding)) Thank you for your ideas and a nice review! It means a lot as we are considering of making a full version out of it. One of idea, for an easy mode - to have a timer with the hints you mentioned. But otherwise it doesn't make so much sense, as a puzzle supposed to train you logic/memory. It's like imagine a maze, where you can see arrows where to go - the whole concept of the maze breaks. So, may be some small hints if you really stuck and have already lost too many lives.
Once again - thank you!
