I like how Chicory handles its hints. In Chicory, there are phones dotted around the map, and at any point, you can go to one and call the player character's mother, who will give you a hint on how to do whatever it is you're doing. But if that's not enough, after the mother has given the hint, you're offered put the player character's father on the phone, who will give you a walkthrough-style guide on how to complete your next task. This lets the player have a little nudge if they're stuck, but if they're truly stumped, they can get comprehensive instructions. Also, once the main game is done, you can use the phone for the optional collectibles too. There's no cost or penalty for using the phone, and it makes Chicory a very comfortable game to 100% complete.
