I don't mind the amount of text, I think it fits with Kin. However, the way it is done seems a bit... robotic?
I'm more curious why it's important to explain the trap. Is this going to go wrong? And if so, wouldn't her falling into a simpler, but better hidden trap be better for story progression than explaining yet another convoluted trap that has a good chance of being explained and then rendered completely useless right afterwards?
Ah well, I used to like the dungeon explanations and the like. The glacial pacing of updates just makes them feel like they are in the way more than them adding anything. I want the story to develop, and these sidetracks make it take even longer. I guess it would've been better for me to have just waited a year and read the ten to twenty updates in one go
But there's an important difference in your reasoning. Scorpion Kin could still be dead, but there are many ways she could have been killed. Indeed, Kin might remember having killed her some other way, and it might even be that she had killed Scorpia that way.
Your theory has the hole deleting the object, deleting the memory of the object, but not, say, a note that says "Kin, you wrote this note just after you dropped a boot into one of the oblivion holes. You used the boot to kick a hole in the wall behind you. You'll want to check and see if the hole is still there, and also see if you can remember the incident." To my mind the boot "writes" the memory of the object into your brain cells in the same way it "writes" a boot print onto a wall.
No, she wouldn't remember a different way of killing her. She still would've killed her in the exact same manner, but she just wouldn't remember how she had done it, because for that she needs the memory of having a tail. The oblivion hole doesn't create new memories, it just erases ones that are related to that particular object (or body part, I guess). Kin would just be confused about how she killed the Scorpion Kin.
