Hope <> we're getting = two different things
Right now it's rather unlikely we'll get another spooky time episode this year.
Fire Lord Zuko
I tested your game, here is some feedback:
I'm a fan of Zuko (and Sokka) but I don't see the reason to make him the mc of this game. But that's just my preference and doesn't belong to the feedback. Anybody who tries to make mods for FET can't do wrong in my book.
positive:
+++ the visit from a certain relative
+++ the visit from a shy person
+++ multiple reasonable story additions
+ no money grind (that's probably a triple + for most)
negative:
--- The text pacing is annoying. I understand you want the player to read the text in a certain way but a fixed pacing is always a bad idea in visual novels. Anyone who wants to read, will do so in his/her own speed.
-- The pacing of Katara's training. You tried to give a reasonable explanation and for a porn game it's probably good for most. But as someone who knows the series the "love on first sight", I don't really buy. Zuko is too much out of character and often behaves childish and renegade, which would somewhat fit for the slave route but not for love.
I get it's pretty hard to write a good story but you had a good thing going on with the shared past of both characters. Maybe expand on that. (Katara trusted Zuko for the first time when he told her of his scar in Ba Sing Se.)
neutral:
Not sure about the added sounds/music. Some are good, some are used too often imo.
I wasn't quite sure which Zuko we play and if he's the same when he's send away by the spirit. From his looks it's the "good" one but from some of his comments it's the restless one. Maybe flesh that out more.
Why is Zuko bad at hunting Moose Lions, he's using fire bending?
Btw., if you need certain art assets to make a scene worth, you could try your luck asking Marty directly. If he has time, and it's easy/fast to do, it's not unlikely he'll help you.
