Playing the full release of Quake for the first time on Nightmare (I actually only played the shareware version!) and man. Episode 1's level design still holds up. Plenty of purposeful misdirection immediately followed by *some* opportunity for the player to let loose for a bit before the next trap

I keep telling people that surprise is one of the most important tools in the level designer's arsenal and episode 1 does NOT stop trying to fake you out at every corner.
