It depends on how complex the game is imo. I can imagine it must be difficult to implement one in a gamejam if there's a need for it, but a simple recurring popup with highlights/arrows and text to explain things wouldn't be too much work.
i had the arrow on the player to go to each objective i just needed to put in some sort of text explaining what to do or something. the thing is i didnt want to slap the "yellow paint" on everything.....
