Non-linearity and world persistency are key aspects of MV games and fans tend to prefer a non-linear experience over a linear one, at least judging by the MV subreddit and various popular YT vids as well as feedback from people I've shown the site to. So why would you not want to know this?
I'm already linking to gameplay and reviews at the bottom of each entry, such info as in the tvtropes blurb is already covered better there (or in this case, you already know it's a metroidvania and that you work with cubes, the latter is in the name and the former is a given with a site like this lol) and the rest on that site is obviously not relevant. As the front page says this is for quick reference and not a full text review or description of each game.
Tip: Don't read what's inside the parenthesis (which I don't use everywhere mind you) if you don't want the details or want to avoid detailed gameplay spoilers. Or just check the list format page if you don't want any of this info, as I mention on the site already.
If you can make an actual suggestion on what to change I'll think about it. But it seems like you just wanted to complain a bit for no particular reason?
