For Engineers, it would be great if you could add a time limit for how long you can stay in the vent for and a cooldown for how many times you can go in it every few seconds, like the vanilla version.
I like the small features Town Of Host: Enhance has: Stopping the start button if needed, stopping the game sooner just in case a player is missing and so on.
Scientist is perfect, because you can adjust the duration and the cooldown of it. Shapeshifter is perfect too, so it should be the same for Engineer.
I know there's Guardian Angel, but not that many people like it and it's rarely on, so we don't need to worry about that.
