>>55059317>Complicated layout with 11 floors>Warp puzzle (which was a novel idea at the time) that naturally compliments this element of it and makes the entire place feel suitably confusing to navigate.>Has a metric shit ton of trainers to potentially wear out the player and further disorient them>The vast majority of these trainers can be skipped if you know what you're doing, so experienced players can avoid the tedium or battle as many as they want for the extra exp>A rival battle AND a boss battle towards the endLiterally PEAK dungeon design, has not been topped since. It has everything you could ask for in a pokemon dungeon and is highly open to variation from playthrough to playthrough.
