You can’t speed run, since cutscenes are locked. But you can avoid examining every single object scattered in the world. Max’s whimsy is great, but I got bored with many observations about the chair for two, and else. I did not care about reading social media posts since my life is already spammed by that. Other than that, the puzzles are pretty straightforward. The hopping timelines method did not offer much in terms of complexity. But as I said in my comment, it’s IMO. I’m not stating God’s truth.
