Slow menu: The menu was usable, it just took 10 seconds to move I think. This is not unique to this game, but it happens to many rpg maker games on mobile and pc (since it doesn't happen to all of them, I believe it can be fixed somehow). I think I didn't have that problem in Town of Passion and Detective Girl of The Steam City, and those games are very heavy. I had that problem in Erolon though. There's games that could run at 120fps on that potato or my phone, and they would still have that issue.
White Dress Duplication: You should consider removing the item from the player's inventory and then adding it to force it on the player
Low quality: I am glad to hear that! and it's interesting, when I go back to play it, it won't be the same.
Cursed Shop items: maybe I didn't know, I don't remember trying it :). I think the game probably mentioned it but I forgot
Black Sailor outfit: great! :D
Dragon cock: I meant an actual dragon, but I like your imagination :) your ideas are always interesting
Reluctant feminity: I think I remember trying that, and it doesn't work since the main character will still be open about things in many dialogues and have more confidence.
More quests: Let me explain further what I had in mind, because it doesn't have to be side-quests while you do dungeons or even inside the dungeon. You can make quests before the dungeons just so the pacing improves, similar to the cowgirl one. These quests would be given by the guild. You can avoid having to balance the game by having these quests occur on the safe areas, revisiting some characters. You technically already have these quests, but they are not handed to you by the guild and no one asks you to do it, they are just part of the world. The reward can be minimal too, could be no exp and some gold. I think at least 1 between each dungeon might be enough to improve the pacing, but it should be obligatory for one of the dungeons because the game said it was not easy to find (I don't remember which), it would help simulate time passing. I was thinking you could revisit previous dungeons, but if that could cause balancing issues then better not.
I won't be playing the game again soon, but hopefully when I do I'll have a setup that will allow me to record my gameplay and maybe debug more :D. Depends on how my life goes. I want to play this when I am less busy and I had finished some of my video projects. I am glad my comments were helpful ^^
Edit: I found the outfit I made :D, I think it's a recolor. I'll give more touches to the outfits when I play again. Make it feel more personal and more me
