I had implemented something like that, but I thought it made it too easy.
Yes, even though it's not obligatory, the more blocks yo take with you, the easier it will be.
I think that's a great mechanic of things being easier the more you bring with you, definitely make that more known (even just in the description) because it's VERY in line with the theme :D
What if I create a help button that gives certain hints when pressed?
