I think you are referring to the optional puzzles , you dont need any coins to beat the game , the optional puzzles and the coins are a layered extra challenge that you dont have to take to enjoy the game.
mmmm based on my guess of what i think you are trying to say i think that's a good point in terms of something that doesn't look optional but it's not trivial to deal with
Hi there! We did our best to make the parts of the game that can be challenging to be skippable; as for the main puzzles, maybe the objectives menu can be of help to you!
