This game is quite enjoyable. Although I am not a fan of the source. But the difficulty is quite... reckless. Even if I don't skip dungeons and grind hard to get at least most of titles for almost each of girls. I like local system of levels, CGs, inventory and resetting dungeons. But I have some issues with it.

I'll tell my thoughts about first 5 dungeons. Because I haven't touch the rest, and, if the difficulty curve here is messed, I might won't endure them:

Okay, the first dungeon (clothes destruction) is interesting, funny. Although I have found only ONE chest with rags. I don't know if it was intentional or if I didn't find the other chests. Kinda boring because instead of rushing to boss I have grinded mobs nearby until the party got the level cap.;

The second (corsets and heels) - okay. But I found that I had walked a circles for hour before I found a way to boss;

The shird one (cursed inventory) is pretty funny and fast. Although somehow Curse remover was not worked. Or maybe I got no idea of how it supposed to work;

The fourth (mummification) forced me to use saves. I used cloaked slave collar on Kyouko, and that broke the run. Falltraps forced to be more careful of the surroundings. I understand why, but I still would like to scream "please be gentle" because the troll equipment;

The fifth (futa and belts) kicked me out. Debuffs are harsh, and the party gets wiped out pretty easily. Labyrinth is confusing (lines on the floor don't help, and teleports are messing up), and party cannot just leave and reset the dungeon (and revive fallen girls, because debuff literally kill them). Only Madoka survived the boss fight, lol.

As for other dungeons. Usually they have specific mechanic that makes walkthrough easy or difficult. "Tentacles and beach" dungeon became hard because party suddenly got "stun parasite". This added random into the boss fight.

"Petplay dungeon" suddenly has confusing maze. Mostly because sometimes you can't return to QB, and get no idea of where to go. It's unfair and sometimes frustrating, but adds some challenge and interest.

To be honest, I got pretty serious into Ero Witches because of challenging and confusing dungeons, and familiar setting. And forgot that it's just parody of "mahou shoujo deconstruction". Due to this I was surprised by talks in "addiction dungeon" and the ending.

I found few bugs. One in "petplay dungeon" when you go downstairs.

Another are glitches in final boss fights. Boss puts straitjackets on girls, but their arms are somehow free.

After playing Ero Dungeons I figured out that it's first game and probe. It's interesting and addicting (sorry for pun), but level-design is frustrating sometimes. So I'm pretty interested and looking forward at Ero Dungeons.
