@Stardust I'm still revising it because it makes me cringe. It's 3000+ words only because I made AI refine and extend the short scenes I couldn't be bothered to extend myself. My friends say it's cringe overall, but they like the fight scenes (that's the part I put the most effort into — 1500 words of my own writing, the AI barely changed them).
For worldbuilding... my head was empty, so I let AI handle a lot of it based on my short input. I'm going for a mix of hard and soft worldbuilding but leaning mostly hard. Economy is definitely a weak point — I don't know what I'm doing there lol. Culture shock is the main comedy I'm playing with.
I spent a lot of time refining the characters (even the extras). The MC contrast is one emotionless sword genius from a medieval world vs. a funny nerdy genius from a sci-fi world.
