I started a new game in MD2, and it took me three attempts to get all the way to the top. And this is only the THIRD DUNGEON IN THE GAME - before you're even given the option to revisit prior dungeons at that. I did remember this game's difficulty being absolutely dreadful, and I also remembered struggling with this place the first time around, but sheesh. This may be the only game in existence that gets this hard while still throwing early-game tutorials at you. (cue neverending list of likewise games in the comments)
Heck, even after returning with slightly higher levels and extra team members to do some missions it was still a pretty scary process. Those Starlys and Doduos just hurt so much, and if you thought abilities like Poison Point were intolerable in FRLG, here you have to contend with Spinaraks, Nidorinas and Nidorinos at a point where your stock of Pecha Berries might not be up to par, and the game keeps throwing RAWST Berries at you instead. Oh, and EVERYTHING seems to trigger Poison Point if it's done at melee range. Even stuff like Ember or Absorb.
