Dungeon 5 was mechanically the most interesting dungeon so far, with the chastity and plug effects forcing a different strategy. Special attacks were often rendered pretty worthless, but regular attacks could be boosted significantly by not being in chastity and not being aroused. Also, all the enemies used regular attacks, which made a tank strategy viable. Focus fire was really bad in earlier dungeons... but by now, Mami has Taunt and Ribbon Guard, and the rest of the party could spend the first round dropping physical defence buffs on her or physical damage debuffs on enemies. Of course, the boss defied this meta by exclusively using special attacks, but I could've easily retooled for that if I wasn't able to win on the first attempt. Getting there was a bit of a grind as I wanted to be sure to check all the doors for loot, but no big deal.
Dungeon 6, which I skipped in my earlier testing, was not my thing fetish-wise, though the gag was admittedly a nice touch. Aside from that, I noticed that Fat seems to be able to go above 100, despite the display capping at 100. Excessively fat girls might claim to be losing Fat every turn, but not actually going below 100, even if protected by a Taunt tank for a longish fight. The problem here is that the Insult attack scales on Fat... and though I don't have access to the raw data, it seems to keep scaling based on Fat beyond 100. So when I tried using a Collar of Confidence to make Mami the designated tank again throughout the dungeon, it worked quite well for a while... but eventually the broccoli enemies became able to one-shot her from nigh-full HP straight to zero through six stacks of Special Defence Up. Fortunately, the Fat Dissolver reduces Fat to an absolute value, which offered a solution; I didn't have further troubles after dissolving away the excess fat. I do note that the game structure led me to expect a chest or two between the boss and the exit, which was not here this time. With only a single, easily-granted title, which everyone had by the time I found and defeated the boss, there wasn't really much else to do... but the absence felt notable anyways, and got me to waste time on a longer search to make sure I wasn't missing something obvious.
(I'd ask about save storage and deletion of saves, since I'm running out at this point, but I understand that's already on the to-do list for next week)
