Gemstone Parkour, Any% Navigationless. My brother came up with this after watching 1 run of the game. Get one gem in every area and navigation is not allowed. All other rules of Any% also apply here.

I'm gonna turn this into "New Category Suggestions (for nerds who don't have discord)" and suggest Gemstone Parkour Courtyard%. You must get all gems in the Courtyard level of Gemstone Parkour. You can not leave the Courtyard area. All other non-contradictory rules of 100% apply here.
