I was thinking that a category where you can't turn could be neat, as you can already set your sensitivity in the game to 0

Escape 0 turnless example:

Every single level has been proven to be beaten with sens 0 but like most other category ideas its just not really necessary so is unlikely to be added

yeah, not very interesting to watch imo due to the lack of interesting strategies available. it doesn't add anything new, just takes away from the depth of the game.
