For what it's worth, you could always ask Max for hints, in every episode. Any time you talked to Max in episodes 1-5, the dialog options you had were always dynamically populated based on what puzzles you had and hadn't yet solved, and you could ask Max about what you were working on. He wouldn't always give a very strong hint, but everything he said was relevant to getting the puzzle solved. In episode 6, those dialog options were moved up one level in the tree, behind a tag that said "I need a hint." It seems that with that change, people finally noticed the Max dialogues, but they were there all along.
Anyway, we like your suggestions, and many similar things have already been discussed for season 2. So, stay tuned
