Thank you so much for the feedback!
I can say that persistence between dungeon isn't going to happen, that's a can of worms I don't want to open. All other things though, I'll take into consideration. I especially want to add more content to dungeon 4 and 5, so I'll keep your feedback in the back of my head. I'll edit this post later to add what I kept from it.
You'll also be pleased to hear that I uploaded version 0.7 a couple minutes ago, so you can try out the new cursed equipment immediately. Let me know (here or on /d/) what you thought of it.
